API v0.6 - Other languages

API v0.6是OSM可编辑API的当前版本，在2009四月17-21日部署。

这个页面和这一版本的API都自2009年四月开始被扩展和更新多次：

  • 2012年三月，小更改
  • 2013年四月，在添加Map Notes API之后
  • 2016年一月，在添加修改集讨论之后
  • 2018年七月，在许多其他较小的向后兼容更改之后
  • 2019年十二月，expand_bbox端点被移除
  • 2020年三月，添加了OSM要素端点的JSON支持
  • 2020年九月，添加了用户详情的JSON支持
  • 2021年二月，不再使用的过时/changes端点被移除
  • 2021年七月，更新了简体中文翻译

大致情况

这个可编辑API是基于RESTful API的想法。更多关于RESTful APIs的信息，查看Wikipedia上的Representational State Transfer页面.

这个API是一个服务器组件，REST请求在这里被处理。REST请求采取HTTP的GET，PUT，POST以及DELETE信息。任何有效载荷都是XML格式的，使用MIME type “text/xml”以及UTF-8字符编码，并且若证书通过HTTP “Accept”头部处理压缩信息，这些可能被压缩至HTTP层。

Requests to modify the database are authorized using HTTP Basic Authorization or OAuth. Read requests do not require authorization (except user details).

API v0.5与API v0.6之间的更新

若您需要下载数据而不是编辑，请查看下载数据 - 您大概会使用Overpass API（也许还有Overpass turbo)，Planet.osm或者导出.

URL + 验证

目前可以使用以下URL访问API： https://api.openstreetmap.org/

在针对API进行软件测试时，您应该考虑使用 https://master.apis.dev.openstreetmap.org/ 而不是实时API。您的实时服务账户不在同一数据库中，因此您可能需要为测试服务创建一个新的用户名和密码；请使用浏览器访问该页面进行注册。

所有更新、创建或删除数据的API调用必须由已验证和授权的用户进行。身份验证可通过使用用户名和密码的HTTP Basic authentication或使用OAuth来实现。

错误代码

HTTP状态代码400（Bad request）
若您在访问API的cgimap版本，当OAuth验证失败返回“Bad OAuth request”时，这个错误代码将被返回。
HTTP状态代码401（Unauthorized）
未成功登录。
HTTP状态代码403（Forbidden）
成功登录但用户被封禁，将会有一个程序显示错误信息（在必要时会被翻译），并在拥有末端用户UI时提供一个访问OSM网站并浏览任何信息的方便的方式。

要素

There are API calls to create, read, update and delete the three basic elements that make up the map data for OpenStreetMap. They each return or expect the data for the elements in a XML format.

变更集

Every modification of one or more of the elements has to reference an open 变更集.

标签

Every element and changeset may have any number of tags. A tag is a Key-Value pair of Unicode strings of up to 255 full unicode characters (not bytes) each.

最大字符串长度

The current rails implementation of the API limits the length of key and value strings for object, changeset and user preference tags, and relation member roles, to a maximum of 255 characters.

Note: the limit is really 255 and NOT 256 characters.

Reliably identifying users

The previous API v0.5 returned only the user display name. The user can update this at any time and there is no history stored for display name changes. This means there was no way to reliably identify which user made a specific change. API v0.6 includes the numeric user ID of the account in addition to the display name. E.g., 

<node id="68" ... user="fred" uid="123" />

This still requires the user to have made his edits public. User ID for users who have previously made anonymous changes will not be visible. In accordance with a recommendation from the OpenStreetMap Foundation Board, anonymous edits are no longer allowed.

Version numbers/optimistic locking

The planet dump, diffs and the API calls for elements will return a version attribute for each Node, Way and Relation. 

<node id="68" ... version="12" />

These version numbers are used for optimistic locking. To upload a new version of an object, the client will need to provide the version of the object it is modifying. If the version supplied is not the same as the server's current version, an error will be returned (HTTP status code 409: Conflict). This means that any client that is updating data will need to save the version numbers of the original data. One element can be updated multiple times during one changeset and its version number is increased each time so there can be multiple history versions of a single element for one changeset.

In addition, clients can now ask for specific versions of an element.

Version numbers will always begin at 1 and increase by 1 every time an element is changed. Clients should not, however, rely on the increase by 1 when updating an element, but instead retrieve the new version number from the server response.

XML格式

主条目：OSM XML

Every XML response from the server is wrapped in an <osm> element unless specified otherwise (e.g., for diff uploads, or changeset downloads). In most of the later examples this wrapper is left out. 

<osm version="0.6" generator="OpenStreetMap server">
	...
	...
</osm>

Every call to the API has to be wrapped in an <osm> element as well but the version and generator attributes can be left out.

JSON格式

主条目：OSM JSON

The OSM API JSON format is based on the Overpass API JSON format description and is supported for the following endpoints:

  • Retrieving map data by bounding box: GET /api/0.6/map
  • Read: GET /api/0.6/[node|way|relation]/#id
  • History: GET /api/0.6/[node|way|relation]/#id/history
  • Version: GET /api/0.6/[node|way|relation]/#id/#version
  • Multi fetch: GET /api/0.6/[nodes|ways|relations]?#parameters
  • Relations for element: GET /api/0.6/[node|way|relation]/#id/relations
  • Ways for node: GET /api/0.6/node/#id/ways
  • Full: GET /api/0.6/[way|relation]/#id/full
  • Details of a user: GET /api/0.6/user/#id
  • Details of multiple users: GET /api/0.6/users?users=#id1,#id2,...,#idn

To request JSON format, either set the HTTP Accept header to application/json, or use a .json URL suffix.

(Github issue)

Faking the correct HTTP methods

Many of the API calls use PUT and DELETE methods, which may not be available in the client HTTP stack you are using. You should complain to the authors of that stack that it is not a full HTTP implementation. If that doesn't work, then there is a work-around by putting the X_HTTP_METHOD_OVERRIDE header with the value of the method you want to simulate. For example, to make curl do a POST, but use the PUT handler, do: 

curl -v -v -d @changeset.osm -H "X_HTTP_METHOD_OVERRIDE: PUT" "http://server/api/0.6/changeset/create"

API呼叫

杂项

可用API版本：GET /api/versions

Returns a list of API versions supported by this instance.

Please note that actual returned values may change at any time and this XML document only serves as an example.

  • Copyright, attribution, and license: referring to legal information

API:

  • Version minimum and maximum are the API call versions that the server will accept.
  • Area maximum is the maximum area in square degrees that can be queried by API calls.
  • Tracepoints per_page is the maximum number of points in a single GPS trace. (Possibly incorrect)
  • Waypoints maximum is the maximum number of nodes that a way may contain.
  • Changesets maximum is the maximum number of combined nodes, ways and relations that can be contained in a changeset.
  • The status element returns either online, readonly or offline for each of the database, API and GPX API. The database field is informational, and the API/GPX-API fields indicate whether a client should expect read and write requests to work (online), only read requests to work (readonly) or no requests to work (offline).

Policy:

  • Imagery blacklist lists all aerial and map sources, which are not permitted for OSM usage due to copyright. Editors must not show these resources as background layer.

提示

  • Note that the URL is versionless. For convenience, the server supports the request /api/0.6/capabilities too, such that clients can use the same URL prefix http:/.../api/0.6 for all requests.
  • Element and relation member ids are currently implementation dependent limited to 64bit signed integers, this should not be a problem :-).

Retrieving map data by bounding box: GET /api/0.6/map

The following command returns:

  • All nodes that are inside a given bounding box and any relations that reference them.
  • All ways that reference at least one node that is inside a given bounding box, any relations that reference them [the ways], and any nodes outside the bounding box that the ways may reference.
  • All relations that reference one of the nodes, ways or relations included due to the above rules. (Does not apply recursively, see explanation below.)
GET /api/0.6/map?bbox=left,bottom,right,top

where:

  • left is the longitude of the left (westernmost) side of the bounding box.
  • bottom is the latitude of the bottom (southernmost) side of the bounding box.
  • right is the longitude of the right (easternmost) side of the bounding box.
  • top is the latitude of the top (northernmost) side of the bounding box.

Note that, while this command returns those relations that reference the aforementioned nodes and ways, the reverse is not true: it does not (necessarily) return all of the nodes and ways that are referenced by these relations. This prevents unreasonably-large result sets. For example, imagine the case where:

  • There is a relation named "England" that references every node in England.
  • The nodes, ways, and relations are retrieved for a bounding box that covers a small portion of England.

While the result would include the nodes, ways, and relations as specified by the rules for the command, including the "England" relation, it would (fortuitously) not include every node and way in England. If desired, the nodes and ways referenced by the "England" relation could be retrieved by their respective IDs.

Also note that ways which intersect the bounding box but have no nodes within the bounding box will not be returned.

错误代码

HTTP status code 400 (Bad Request)
When any of the node/way/relation limits are exceeded, in particular if the call would return more than 50'000 nodes. See above for other uses of this code.
HTTP status code 509 (Bandwidth Limit Exceeded)
"Error: You have downloaded too much data. Please try again later." See Developer FAQ.

Retrieving permissions: GET /api/0.6/permissions

Returns the permissions granted to the current API connection.

  • If the API client is not authorized, an empty list of permissions will be returned.
  • If the API client uses Basic Auth, the list of permissions will contain all permissions.
  • If the API client uses OAuth 1.0a, the list will contain the permissions actually granted by the user.
  • If the API client uses OAuth 2.0, the list will be based on the granted scopes.

Note that for compatibility reasons, all OAuth 2.0 scopes will be prefixed by "allow_", e.g. scope "read_prefs" will be shown as permission "allow_read_prefs". 

GET /api/0.6/permissions

回应

Returns the single permissions element containing the permission tags (content type text/xml) 

<?xml version="1.0" encoding="UTF-8"?>
<osm version="0.6" generator="OpenStreetMap server">
	<permissions>
		<permission name="allow_read_prefs"/>
		...
		<permission name="allow_read_gpx"/>
		<permission name="allow_write_gpx"/>
	</permissions>
</osm>

提示

Currently the following permissions can appear in the result, corresponding directly to the ones used in the OAuth 1.0a application definition:

  • allow_read_prefs (read user preferences)
  • allow_write_prefs (modify user preferences)
  • allow_write_diary (create diary entries, comments and make friends)
  • allow_write_api (modify the map)
  • allow_read_gpx (read private GPS traces)
  • allow_write_gpx (upload GPS traces)
  • allow_write_notes (modify notes)

变更集

To make it easier to identify related changes the concept of changesets is introduced. Every modification of the standard OSM elements has to reference an open changeset. A changeset may contain tags just like the other elements. A recommended tag for changesets is the key comment=* with a short human readable description of the changes being made in that changeset, similar to a commit message in a revision control system. A new changeset can be opened at any time and a changeset may referenced from multiple API calls. Because of this it can be closed manually as the server can't know when one changeset ends and another should begin. To avoid stale open changesets a mechanism is implemented to automatically close changesets upon one of the following three conditions:

  • More than 10,000 edits on a single changeset See more specific limits
  • The changeset has been open for more than 24 hours
  • There have been no changes/API calls related to a changeset in 1 hour (i.e., idle timeout)

Changesets are specifically not atomic - elements added within a changeset will be visible to other users before the changeset is closed. Given how many changes might be uploaded in one step it's not feasible. Instead optimistic locking is used as described above. Anything submitted to the server in a single request will be considered atomically. To achieve transactionality for multiple changes there is the new diff upload API call.

Changesets facilitate the implementation of rollbacks. By providing insight into the changes committed by a single person it becomes easier to identify the changes made, rather than just rolling back a whole region. Direct support for rollback will not be in the API, instead they will be a form of reverse merging, where client can download the changeset, examine the changes and then manipulate the API to obtain the desired results. Rolling back a changeset can be be an extremely complex process especially if the rollback conflicts with other changes made in the mean time; we expect (hope) that in time, expert applications will be created that make rollback on various levels available to the average user.

To support easier usage, the server stores a bounding box for each changeset and allows users to query changesets in an area. This will be calculated by the server, since it needs to look up the relevant nodes anyway. Client should note that if people make many small changes in a large area they will be easily matched. In this case clients should examine the changeset directly to see if it truly overlaps. A client can expand the bounding box manually using an API call, which can be useful when the client already knows the full extent of the data it is about to upload.

It is not possible to delete changesets at the moment, even if they don't contain any changes. The server may at a later time delete changesets which are closed and which do not contain any changes. This is not yet implemented.

Bounding box computation

This is how the API computes the bounding box associated with a changeset:

  • Nodes: Any change to a node, including deletion, adds the node's old and new location to the bbox.
  • Ways: Any change to a way, including deletion, adds all of the way's nodes to the bbox.
  • Relations:
    • adding or removing nodes or ways from a relation causes them to be added to the changeset bounding box.
    • adding a relation as a member or changing tag values causes all node and way members to be added to the bounding box.
    • this is similar to how the map call does things and is reasonable on the assumption that adding or removing members doesn't materially change the rest of the relation.

As an optimisation the server will create a buffer slightly larger than the objects to avoid having to update the bounding box too often. Thus a changeset may have a different bounding box than its reversion, and the distance between bounding box and the next node may not be constant for all four directions.

创建：PUT /api/0.6/changeset/create

The payload of a changeset creation request is the metadata of this changeset. The body of the request has to include one or more changeset elements, which optionally include an arbitrary number of tags (such as 'comment', 'created_by", ...). All changeset elements need to be enclosed in an osm element. 

<osm>
	<changeset>
		<tag k="created_by" v="JOSM 1.61"/>
		<tag k="comment" v="Just adding some streetnames"/>
		...
	</changeset>
	...
</osm>

If there are multiple changeset elements in the XML the tags from all of them are used, later ones overriding the earlier ones in case of duplicate keys.

Response

The ID of the newly created changeset with a content type of text/plain

Error codes

HTTP status code 400 (Bad Request)
When there are errors parsing the XML
HTTP status code 405 (Method Not Allowed)
If the request is not a HTTP PUT request

Notes

Any number of possibly editor-specific, tags are allowed. An editor might, for example, automatically include information about which background image was used, or even a bit of internal state information that will make it easier to revisit the changeset with the same editor later, etc.

Clients should include a created_by=* tag. Clients are advised to make sure that a comment=* is present, which the user has entered. It is optional at the moment but this might change in later API versions. Clients should not automatically generate the comment tag, as this tag is for the end-user to describe their changes. Clients may add any other tags as they see fit.

Read: GET /api/0.6/changeset/#id?include_discussion=true

Returns the changeset with the given id in OSM-XML format. 

<osm>
	<changeset id="10" user="fred" uid="123" created_at="2008-11-08T19:07:39+01:00" open="true" min_lon="7.0191821" min_lat="49.2785426" max_lon="7.0197485" max_lat="49.2793101">
		<tag k="created_by" v="JOSM 1.61"/>
		<tag k="comment" v="Just adding some streetnames"/>
		...
		<discussion>
			<comment date="2015-01-01T18:56:48Z" uid="1841" user="metaodi">
				<text>Did you verify those street names?</text>
			</comment>
			<comment date="2015-01-01T18:58:03Z" uid="123" user="fred">
				<text>sure!</text>
			</comment>
			...
		</discussion>
	</changeset>
</osm>

Parameters

id
The id of the changeset to retrieve
(new) include_discussion
Indicates whether the result should contain the changeset discussion or not. If this parameter is set to anything, the discussion is returned. If it is empty or omitted, the discussion will not be in the result.

Response

Returns the single changeset element containing the changeset tags with a content type of text/xml

Error codes

HTTP status code 404 (Not Found)
When no changeset with the given id could be found

Notes

  • The uid might not be available for changesets auto generated by the API v0.5 to API v0.6 transition?
  • The bounding box attributes will be missing for an empty changeset.
  • The changeset bounding box is a rectangle that contains the bounding boxes of all objects changed in this changeset. It is not necessarily the smallest possible rectangle that does so.
  • This API call only returns information about the changeset itself but not the actual changes made to elements in this changeset. To access this information use the download API call.

Update: PUT /api/0.6/changeset/#id

For updating tags on the changeset, e.g. changeset comment=foo.

Payload should be an OSM document containing the new version of a single changeset. Bounding box, update time and other attributes are ignored and cannot be updated by this method. Only those tags provided in this call remain in the changeset object. For updating the bounding box see the expand_bbox method. 

<osm>
	<changeset>
		<tag k="comment" v="Just adding some streetnames and a restaurant"/>
	</changeset>
</osm>

Parameters

id
The id of the changeset to update. The user issuing this API call has to be the same that created the changeset

Response

An OSM document containing the new version of the changeset with a content type of text/xml

Error codes

HTTP status code 400 (Bad Request)
When there are errors parsing the XML
HTTP status code 404 (Not Found)
When no changeset with the given id could be found
HTTP status code 405 (Method Not Allowed)
If the request is not a HTTP PUT request
HTTP status code 409 (Conflict) - text/plain
If the changeset in question has already been closed (either by the user itself or as a result of the auto-closing feature). A message with the format "The changeset #id was closed at #closed_at." is returned
Or if the user trying to update the changeset is not the same as the one that created it

Notes

Unchanged tags have to be repeated in order to not be deleted.

Close: PUT /api/0.6/changeset/#id/close

Closes a changeset. A changeset may already have been closed without the owner issuing this API call. In this case an error code is returned.

Parameters

id
The id of the changeset to close. The user issuing this API call has to be the same that created the changeset.

Response

Nothing is returned upon successful closing of a changeset (HTTP status code 200)

Error codes

HTTP status code 404 (Not Found)
When no changeset with the given id could be found
HTTP status code 405 (Method Not Allowed)
If the request is not a HTTP PUT request
HTTP status code 409 (Conflict) - text/plain
If the changeset in question has already been closed (either by the user itself or as a result of the auto-closing feature). A message with the format "The changeset #id was closed at #closed_at." is returned
Or if the user trying to update the changeset is not the same as the one that created it

Download: GET /api/0.6/changeset/#id/download

Returns the OsmChange document describing all changes associated with the changeset.

Parameters

id
The id of the changeset for which the OsmChange is requested.

Response

The OsmChange XML with a content type of text/xml.

Error codes

HTTP status code 404 (Not Found)
When no changeset with the given id could be found

Notes

  • The result of calling this may change as long as the changeset is open.
  • The elements in the OsmChange are sorted by timestamp and version number.

Expand Bounding Box: POST /api/0.6/changeset/#id/expand_bbox (deprecated, gone)

Note: This endpoint was removed in December 2019. See this GitHub issue.

Query: GET /api/0.6/changesets

This is an API method for querying changesets. It supports querying by different criteria.

Where multiple queries are given the result will be those which match all of the requirements. The contents of the returned document are the changesets and their tags. To get the full set of changes associated with a changeset, use the download method on each changeset ID individually.

Modification and extension of the basic queries above may be required to support rollback and other uses we find for changesets.

This call returns at most 100 changesets matching criteria, it returns latest changesets ordered by created_at[1].

Parameters

bbox=min_lon,min_lat,max_lon,max_lat (W,S,E,N)
Find changesets within the given bounding box
user=#uid or display_name=#name
Find changesets by the user with the given user id or display name. Providing both is an error.
time=T1
Find changesets closed after T1
time=T1,T2
Find changesets that were closed after T1 and created before T2. In other words, any changesets that were open at some time during the given time range T1 to T2.
open=true
Only finds changesets that are still open but excludes changesets that are closed or have reached the element limit for a changeset (10.000 at the moment[2])
closed=true
Only finds changesets that are closed or have reached the element limit
changesets=#cid{,#cid}
Finds changesets with the specified ids (since 2013-12-05)

Time format: Anything that this Ruby function will parse. The default str is ’-4712-01-01T00:00:00+00:00’; this is Julian Day Number day 0.

Response

Returns a list of all changeset ordered by creation date. The <osm> element may be empty if there were no results for the query. The response is sent with a content type of text/xml.

Error codes

HTTP status code 400 (Bad Request) - text/plain
On misformed parameters. A text message explaining the error is returned. In particular, trying to provide both the UID and display name as user query parameters will result in this error.
HTTP status code 404 (Not Found)
When no user with the given uid or display_name could be found.

Notes

  • Only changesets by public users are returned.
  • Returns at most 100 changesets

Diff upload: POST /api/0.6/changeset/#id/upload

With this API call files in the OsmChange format can be uploaded to the server. This is guaranteed to be running in a transaction. So either all the changes are applied or none.

To upload an OSC file it has to conform to the OsmChange specification with the following differences:

  • each element must carry a changeset and a version attribute, except when you are creating an element where the version is not required as the server sets that for you. The changeset must be the same as the changeset ID being uploaded to.
  • a <delete> block in the OsmChange document may have an if-unused attribute (the value of which is ignored). If this attribute is present, then the delete operation(s) in this block are conditional and will only be executed if the object to be deleted is not used by another object. Without the if-unused, such a situation would lead to an error, and the whole diff upload would fail. Setting the attribute will also cause deletions of already deleted objects to not generate an error.
  • OsmChange documents generally have user and uid attributes on each element. These are not required in the document uploaded to the API.

Parameters

id
The ID of the changeset this diff belongs to.
POST data
The OsmChange file data

Response

If a diff is successfully applied a XML (content type text/xml) is returned in the following format 

<diffResult generator="OpenStreetMap Server" version="0.6">
	<node|way|relation old_id="#" new_id="#" new_version="#"/>
	...
</diffResult>

with one element for every element in the upload. Note that this can be counter-intuitive when the same element has appeared multiple times in the input then it will appear multiple times in the output.

Attribute create modify delete
old_id same as uploaded element.
new_id new ID same as uploaded not present
new_version new version not present

Error codes

HTTP status code 400 (Bad Request) - text/plain
When there are errors parsing the XML. A text message explaining the error is returned.
When an placeholder ID is missing or not unique (this will occur for circular relation references)
HTTP status code 404 (Not Found)
When no changeset with the given id could be found
Or when the diff contains elements that could not be found for the given id
HTTP status code 405 (Method Not Allowed)
If the request is not a HTTP POST request
HTTP status code 409 (Conflict) - text/plain
If the changeset in question has already been closed (either by the user itself or as a result of the auto-closing feature). A message with the format "The changeset #id was closed at #closed_at." is returned
If, while uploading, the max. size of the changeset is exceeded. A message with the format "The changeset #id was closed at #closed_at." is returned
Or if the user trying to update the changeset is not the same as the one that created it
Or if the diff contains elements with changeset IDs which don't match the changeset ID that the diff was uploaded to
Or any of the error messages that could occur as a result of a create, update or delete operation for one of the elements
Other status codes
Any of the error codes and associated messages that could occur as a result of a create, update or delete operation for one of the elements
See the according sections in this page

Notes

  • Processing stops at the first error, so if there are multiple conflicts in one diff upload, only the first problem is reported.
  • Refer to /api/capabilities --> changesets -> maximum_elements for the maximum number of changes permitted in a changeset.
  • There is currently no limit in the diff size on the Rails port. CGImap limits diff size to 50MB (uncompressed size).
  • Forward referencing of placeholder ids is not permitted and will be rejected by the API.

Elements

There are create, read, update and delete calls for all of the three basic elements in OpenStreetMap (Nodes, Ways and Relations). These calls are very similar except for the payload and a few special error messages so they are documented only once.

Create: PUT /api/0.6/[node|way|relation]/create

Creates a new element of the specified type. Note that the entire request should be wrapped in a <osm>...</osm> element.

A Node: 

<osm>
	<node changeset="12" lat="..." lon="...">
		<tag k="note" v="Just a node"/>
		...
	</node>
</osm>

A Way: 

<osm>
	<way changeset="12">
		<tag k="note" v="Just a way"/>
		...
		<nd ref="123"/>
		<nd ref="4345"/>
		...
	</way>
</osm>

A Relation: 

<osm>
	<relation changeset="12">
		<tag k="note" v="Just a relation"/>
		...
		<member type="node" role="stop" ref="123"/>
		<member type="way" ref="234"/>
	</relation>
</osm>

If multiple elements are provided only the first is created. The rest is discarded (this behavior differs from changeset creation).

Response

The ID of the newly created element (content type is text/plain)

Error codes

HTTP status code 400 (Bad Request) - text/plain
When there are errors parsing the XML. A text message explaining the error is returned.
When a changeset ID is missing (unfortunately the error messages are not consistent)
When a node is outside the world
When there are too many nodes for a way
HTTP status code 405 (Method Not Allowed)
If the request is not a HTTP PUT request
HTTP status code 409 (Conflict) - text/plain
If the changeset in question has already been closed (either by the user itself or as a result of the auto-closing feature). A message with the format "The changeset #id was closed at #closed_at." is returned
Or if the user trying to update the changeset is not the same as the one that created it
HTTP status code 412 (Precondition Failed)
When a way has nodes that do not exist or are not visible (i.e. deleted): "Way #{id} requires the nodes with id in (#{missing_ids}), which either do not exist, or are not visible."
When a relation has elements that do not exist or are not visible: "Relation with id #{id} cannot be saved due to #{element} with id #{element.id}"

Notes

  • This updates the bounding box of the changeset.
  • The role attribute for relations is optional. An empty string is the default.

Read: GET /api/0.6/[node|way|relation]/#id

Returns the XML representation of the element.

Example

/api/0.6/node/12345

Will get the node with id 12345

Response

XML representing the element, wrapped in an <osm> element: 

<osm>
	<node id="123" lat="..." lon="..." version="142" changeset="12" user="fred" uid="123" visible="true" timestamp="2005-07-30T14:27:12+01:00">
		<tag k="note" v="Just a node"/>
		...
	</node>
</osm>

Error codes

HTTP status code 404 (Not Found)
When no element with the given id could be found
HTTP status code 410 (Gone)
If the element has been deleted

Update: PUT /api/0.6/[node|way|relation]/#id

Updates data from a preexisting element. A full representation of the element as it should be after the update has to be provided. Any tags, way-node refs, and relation members that remain unchanged must be in the update as well. A version number must be provided as well, it must match the current version of the element in the database.

This example is an update of the node 4326396331, updating the version 1 to alter existing tags. This change is made while the changeset with id 188021 is still open: 

<osm>
	<node changeset="188021" id="4326396331" lat="50.4202102" lon="6.1211032" version="1" visible="true">
		<tag k="foo" v="barzzz" />
	</node>
</osm>

Response

Returns the new version number with a content type of text/plain.

Error codes

HTTP status code 400 (Bad Request) - text/plain
When there are errors parsing the XML. A text message explaining the error is returned. This can also happen if you forget to pass the Content-Length header.
When a changeset ID is missing (unfortunately the error messages are not consistent)
When a node is outside the world
When there are too many nodes for a way
HTTP status code 409 (Conflict) - text/plain
When the version of the provided element does not match the current database version of the element
If the changeset in question has already been closed (either by the user itself or as a result of the auto-closing feature). A message with the format "The changeset #id was closed at #closed_at." is returned
Or if the user trying to update the changeset is not the same as the one that created it
HTTP status code 404 (Not Found)
When no element with the given id could be found
HTTP status code 412 (Precondition Failed)
When a way has nodes that do not exist or are not visible (i.e. deleted): "Way #{id} requires the nodes with id in (#{missing_ids}), which either do not exist, or are not visible."
When a relation has elements that do not exist or are not visible: "Relation with id #{id} cannot be saved due to #{element} with id #{element.id}"

Notes

  • This updates the bounding box of the changeset.

Delete: DELETE /api/0.6/[node|way|relation]/#id

Expects a valid XML representation of the element to be deleted.

For example: 

<osm>
	<node id="..." version="..." changeset="..." lat="..." lon="..." />
</osm>

Where the node ID in the XML must match the ID in the URL, the version must match the version of the element you downloaded and the changeset must match the ID of an open changeset owned by the current authenticated user. It is allowed, but not necessary, to have tags on the element except for lat/long tags which are required, without lat+lon the server gives 400 Bad request.

Response

Returns the new version number with a content type of text/plain.

Error codes

HTTP status code 400 (Bad Request) - text/plain
When there are errors parsing the XML. A text message explaining the error is returned.
When a changeset ID is missing (unfortunately the error messages are not consistent)
When a node is outside the world
When there are too many nodes for a way
When the version of the provided element does not match the current database version of the element
HTTP status code 404 (Not Found)
When no element with the given id could be found
HTTP status code 409 (Conflict) - text/plain
If the changeset in question has already been closed (either by the user itself or as a result of the auto-closing feature). A message with the format "The changeset #id was closed at #closed_at." is returned
Or if the user trying to update the changeset is not the same as the one that created it
HTTP status code 410 (Gone)
If the element has already been deleted
HTTP status code 412 (Precondition Failed)
When a node is still used by a way: Node #{id} is still used by way #{way.id}.
When a node is still member of a relation: Node #{id} is still used by relation #{relation.id}.
When a way is still member of a relation: Way #{id} still used by relation #{relation.id}.
When a relation is still member of another relation: The relation #{id} is used in relation #{relation.id}.
Note when returned as a result of a OsmChange upload operation the error messages contain a spurious plural "s" as in "... still used by ways ...", "... still used by relations ..." even when only 1 way or relation id is returned, as this implies multiple ids can be returned if the deleted object was/is a member of multiple parent objects, these ids are seperated by commas.

Notes

  • In earlier API versions no payload was required. It is needed now because of the need for changeset IDs and version numbers.

History: GET /api/0.6/[node|way|relation]/#id/history

Retrieves all old versions of an element.

Error codes

HTTP status code 404 (Not Found)
When no element with the given id could be found

Version: GET /api/0.6/[node|way|relation]/#id/#version

Retrieves a specific version of the element.

Error codes

HTTP status code 403 (Forbidden)
When the version of the element is not available (due to redaction)
HTTP status code 404 (Not Found)
When no element with the given id could be found

Multi fetch: GET /api/0.6/[nodes|ways|relations]?#parameters

Allows a user to fetch multiple elements at once.

Parameters

[nodes|ways|relations]=comma separated list
The parameter has to be the same in the URL (e.g. /api/0.6/nodes?nodes=123,456,789)
Version numbers for each object may be optionally provided following a lowercase "v" character, e.g. /api/0.6/nodes?nodes=421586779v1,421586779v2

Error codes

HTTP status code 400 (Bad Request)
On a malformed request (parameters missing or wrong)
HTTP status code 404 (Not Found)
If one of the elements could not be found (By "not found" is meant never existed in the database, if the object was deleted, it will be returned with the attribute visible="false")
HTTP status code 414 (Request-URI Too Large)
If the URI was too long (tested to be > 8213 characters in the URI, or > 725 elements for 10 digit IDs when not specifying versions)

Relations for element: GET /api/0.6/[node|way|relation]/#id/relations

Returns a XML document containing all (not deleted) relations in which the given element is used.

Notes

  • There is no error if the element does not exist.
  • If the element does not exist or it isn't used in any relations an empty XML document is returned (apart from the <osm> elements)

Ways for node: GET /api/0.6/node/#id/ways

Returns a XML document containing all the (not deleted) ways in which the given node is used.

Notes

  • There is no error if the node does not exist.
  • If the node does not exist or it isn't used in any ways an empty XML document is returned (apart from the <osm> elements)

Full: GET /api/0.6/[way|relation]/#id/full

This API call retrieves a way or relation and all other elements referenced by it

  • For a way, it will return the way specified plus the full XML of all nodes referenced by the way.
  • For a relation, it will return the following:
    • The relation itself
    • All nodes, ways, and relations that are members of the relation
    • Plus all nodes used by ways from the previous step
    • The same recursive logic is not applied to relations. This means: If relation r1 contains way w1 and relation r2, and w1 contains nodes n1 and n2, and r2 contains node n3, then a "full" request for r1 will give you r1, r2, w1, n1, and n2. Not n3.

Error codes

HTTP status code 404 (Not Found)
When no element with the given id could be found
HTTP status code 410 (Gone)
If the element has been deleted

Redaction: POST /api/0.6/[node|way|relation]/#id/#version/redact?redaction=#redaction_id

This is an API method originaly created for the ODbL license change to hide contributions from users that did not accept the new CT/licence. It is now used by the DWG to hide old versions of elements containing data privacy or copyright infringements. All API retrieval request for the element #version will return an HTTP error 403.

Notes

Error Codes

HTTP status code 400 (Bad Request)
"Cannot redact current version of element, only historical versions may be redacted."

GPS traces

In violation of the GPX standard when downloading public GPX traces through the API, all waypoints of non-trackable traces are randomized (or rather sorted by lat/lon) and delivered as one trackSegment for privacy reasons.

Get GPS Points: Get /api/0.6/trackpoints?bbox=left,bottom,right,top&page=pageNumber

Use this to retrieve the GPS track points that are inside a given bounding box (formatted in a GPX format).

where:

  • left, bottom, right, and top are used the same way as they are in the command to retrieve nodes, ways, and relations.
  • pageNumber specifies which group of 5,000 points, or page, to return. Since the command does not return more than 5,000 points at a time, this parameter must be incremented—and the command sent again (using the same bounding box)—in order to retrieve all of the points for a bounding box that contains more than 5,000 points. When this parameter is 0 (zero), the command returns the first 5,000 points; when it is 1, the command returns points 5,001–10,000, etc.

Examples

Retrieve the first 5,000 points for a bounding box: 

https://api.openstreetmap.org/api/0.6/trackpoints?bbox=0,51.5,0.25,51.75&page=0

Retrieve the next 5,000 points (points 5,001–10,000) for the same bounding box: 

https://api.openstreetmap.org/api/0.6/trackpoints?bbox=0,51.5,0.25,51.75&page=1
Response
  • This response is NOT wrapped in an OSM xml parent element.
  • The file format is GPX Version 1.0 which is not the current version. Verify that your tools support it.

Create: POST /api/0.6/gpx/create

Use this to upload a GPX file or archive of GPX files. Requires authentication.

The following parameters are required in a multipart/form-data HTTP message:

parameter description
file The GPX file containing the track points. Note that for successful processing, the file must contain trackpoints (<trkpt>), not only waypoints, and the trackpoints must have a valid timestamp. Since the file is processed asynchronously, the call will complete successfully even if the file cannot be processed. The file may also be a .tar, .tar.gz or .zip containing multiple gpx files, although it will appear as a single entry in the upload log.
description The trace description. Cannot be empty.
tags A string containing tags for the trace. Can be empty.
public 1 if the trace is public, 0 if not. This exists for backwards compatibility only - the visibility parameter should now be used instead. This value will be ignored if visibility is also provided.
visibility One of the following: private, public, trackable, identifiable (for explanations see OSM trace upload page or Visibility of GPS traces)

Response:

A number representing the ID of the new gpx

Methods for user data

Details of a user

This API method was added in September 2012 (code).

You can get the home location and the displayname of the user, by using 

GET /api/0.6/user/#id

this returns for example 

<osm version="0.6" generator="OpenStreetMap server">
	<user id="12023" display_name="jbpbis" account_created="2007-08-16T01:35:56Z">

		<blocks>
			<received count="0" active="0"/>
		</blocks>
	</user>
</osm>

or an empty file if no user found for given identifier.

Details of multiple users

This API method was added in July 2018 (code).

You can get the details of a number of users via 

GET /api/0.6/users?users=#id1,#id2,...,#idn

this returns for example 

<osm version="0.6" generator="OpenStreetMap server">
	<user id="12023" display_name="jbpbis" account_created="2007-08-16T01:35:56Z">

or an empty file if no user found for given identifier.

Details of the logged-in user

You can get the home location and the displayname of the user, by using 

GET /api/0.6/user/details

this returns an XML document of the from 

<osm version="0.6" generator="OpenStreetMap server">
	<user display_name="Max Muster" account_created="2006-07-21T19:28:26Z" id="1234">

		</messages>
	</user>
</osm>

The messages section has been available since mid-2013. It provides a basic counts of received, sent, and unread osm messages.

Preferences of the logged-in user

The OSM server supports storing arbitrary user preferences. This can be used by editors, for example, to offer the same configuration wherever the user logs in, instead of a locally-stored configuration.

You can retrieve the list of current preferences using 

 GET /api/0.6/user/preferences

this returns an XML document of the form 

<osm version="0.6" generator="OpenStreetMap server">
	<preferences>
		<preference k="somekey" v="somevalue" />
		...
	</preferences>
</osm>

 PUT /api/0.6/user/preferences

The same structure in the body of the a PUT will upload preferences. All existing preferences are replaced by the newly uploaded set. 

 GET /api/0.6/user/preferences/[your_key] (without the brackets)

Returns a string with that preference's value. 

 PUT /api/0.6/user/preferences/[your_key] (without the brackets)

Will set a single preference's value to a string passed as the content of the request. 

 PUT /api/0.6/user/preferences/[your_key]

in this instance, the payload of the request should only contain the value of the preference, i.e. not XML formatted.

The PUT call returns HTTP response code 406 (not acceptable) if the same key occurs more than once, and code 413 (request entity too large) if you try to upload more than 150 preferences at once. The sizes of the key and value are limited to 255 characters.

A single preference entry can be deleted with 

 DELETE /api/0.6/user/preferences/[your_key]

Map Notes API

This provides access to the notes feature, which allows users to add geo-referenced textual "post-it" notes. This feature was not originally in the API 0.6 and was only added later ( 04/23/2013 in commit 0c8ad2f86edefed72052b402742cadedb0d674d9 )

Retrieving notes data by bounding box: GET /api/0.6/notes

Returns the existing notes in the specified bounding box. The notes will be ordered by the date of their last change, the most recent one will be first. The list of notes can be returned in several different forms (e.g. as executable JavaScript, XML, RSS, json and GPX) depending on the file extension.

Note: the XML format returned by the API is different from the, equally undocumented, format used for "osm" format files, available from planet.openstreetmap.org, and as output from JOSM and Vespucci.


URL: https://api.openstreetmap.org/api/0.6/notes?bbox=left,bottom,right,top (example)
Return type: application/xml


Parameter Description Allowed values Default value
bbox Coordinates for the area to retrieve the notes from Floating point numbers in degrees, expressing a valid bounding box, not larger than the configured size limit, 25 square degrees [1], not overlapping the dateline. none, parameter required
limit Specifies the number of entries returned at max A value of between 1 and 10000 is valid 100 is the default
closed Specifies the number of days a note needs to be closed to no longer be returned A value of 0 means only open notes are returned. A value of -1 means all notes are returned. 7 is the default

You can specify the format you want the results returned as by specifying a file extension. E.g. example to get results in json. Currently the format RSS, XML, json and gpx are supported.

The comment properties [uid, user, user_url] will be omitted if the comment was anonymous.

When NOT to use the API

For bulk upload scripts or data modification, the direct API use may not be the proper mechanism. The modern version of creating a bulk upload or modification script is to build a change set, load it into an editor like JOSM, and verify the work prior to commit. You can also use the API to upload a change set in an atomic manner. See also: Change File Formats, Import

The API is primarily intended for editing. For read-only purposes or projects, see API usage policy.

Semantic versioning

At the time of first deployment, semantic versioning (with a minor version number) wasn't an established concept. As a result, the API doesn't follow this scheme. Many applications wouldn't be able to handle minor version number changes correctly, thus no attempt is made to add it, although the current version can be thought of as being 0.6.7.
