Python wrapper for the OSM API

Project description


Build osmapi Version License Coverage Code style: black pre-commit

Python wrapper for the OSM API (requires Python >= 3.8)


Install osmapi from PyPi by using pip:

pip install osmapi


The documentation is generated using pdoc and can be viewed online.

The build the documentation locally, you can use

make docs

This project uses GitHub Pages to publish its documentation. To update the online documentation, you need to re-generate the documentation with the above command and update the master branch of this repository.


To test this library, please create an account on the development server of OpenStreetMap (

Check the examples directory to find more example code.

Read from OpenStreetMap

>>> import osmapi
>>> api = osmapi.OsmApi()
>>> print(api.NodeGet(123))
{u'changeset': 532907, u'uid': 14298,
u'timestamp': u'2007-09-29T09:19:17Z',
u'lon': 10.790009299999999, u'visible': True,
u'version': 1, u'user': u'Mede',
u'lat': 59.9503044, u'tag': {}, u'id': 123}


import osmapi
api = osmapi.OsmApi(api="", username = "you", password = "***")
api = osmapi.OsmApi(username = "you", passwordfile = "/etc/mypasswords")
api = osmapi.OsmApi(passwordfile = "/etc/mypasswords") # if only the passwordfile is specified, the credentials on the first line of the file will be used

Note: Each line in the password file should have the format user:password

Write to OpenStreetMap

>>> import osmapi
>>> api = osmapi.OsmApi(api="", username = u"metaodi", password = u"*******")
>>> api.ChangesetCreate({u"comment": u"My first test"})
>>> print(api.NodeCreate({u"lon":1, u"lat":1, u"tag": {}}))
{u'changeset': 532907, u'lon': 1, u'version': 1, u'lat': 1, u'tag': {}, u'id': 164684}
>>> api.ChangesetClose()

OAuth authentication

Username/Password authentication will be deprecated in 2024 (see official OWG announcemnt for details). In order to use this library in the future, you'll need to use OAuth 2.0.

To use OAuth 2.0, you must register an application with an OpenStreetMap account, either on the development server or on the production server. Once this registration is done, you'll get a client_id and a client_secret that you can use to authenticate users.

Example code using requests-oauth2client:

from requests_oauth2client import OAuth2Client, OAuth2AuthorizationCodeAuth
import requests
import webbrowser
import osmapi
import os

client_id = "<client_id>"
client_secret = "<client_secret>"

# special value for redirect_uri for non-web applications
redirect_uri = "urn:ietf:wg:oauth:2.0:oob"

authorization_base_url = ""
token_url = ""

oauth2client = OAuth2Client(

# open OSM website to authrorize user using the write_api and write_notes scope
scope = ["write_api", "write_notes"]
az_request = oauth2client.authorization_request(scope=scope)
print(f"Authorize user using this URL: {az_request.uri}")

# create a new requests session using the OAuth authorization
auth_code = input("Paste the authorization code here: ")
auth = OAuth2AuthorizationCodeAuth(
oauth_session = requests.Session()
oauth_session.auth = auth

# use the custom session
api = osmapi.OsmApi(
with api.Changeset({"comment": "My first test"}) as changeset_id:
    print(f"Part of Changeset {changeset_id}")
    node1 = api.NodeCreate({"lon": 1, "lat": 1, "tag": {}})

Note about imports / automated edits

Scripted imports and automated edits should only be carried out by those with experience and understanding of the way the OpenStreetMap community creates maps, and only with careful planning and consultation with the local community.

See the Import/Guidelines and Automated Edits/Code of Conduct for more information.


If you want to help with the development of osmapi, you should clone this repository and install the requirements:

make deps

Better yet use the provided script to create a virtual env and install this package in it.

You can lint the source code using this command:

make lint

And if you want to reformat the files (using the black code style) simply run:

make format

To run the tests use the following command:

make test


To create a new release, follow these steps (please respect Semantic Versioning):

  1. Adapt the version number in osmapi/
  2. Update the CHANGELOG with the version
  3. Re-build the documentation (make docs)
  4. Create a pull request to merge develop into master (make sure the tests pass!)
  5. Create a new release/tag on GitHub (on the master branch)
  6. The publication on PyPI happens via GitHub Actions on every tagged commit


This project was orginally developed by Etienne Chové. This repository is a copy of the original code from SVN (, with the goal to enable easy contribution via GitHub and release of this package via PyPI.
