This endpoint downloads OpenStreetMap features that are inside a circle, centered at address extending radius meters out.

For example, these are the results for building=* within radius=1000 meters of San Francisco International Airport’s address:

openstreetmap features in radius

You can filter for any tag in the database, either as key=value or key=*, and can chain tags if you need 2+ tags.

Request Parameters


This is a list of tags in the form key=value to filter features for. All features extracted will satisfy each of the passed tags given by this parameter.

This tag list can be created by forming an array of key=value items and joining them into one string with the & character.

Because both = and & are reserved characters in URIs, this list must be URL encoded.

An example list of tags could be leisure=park and name=Westglen Park. This matches parks that have the name Westglen Park. To set this parameter, we’ll URL encode leisure=park&name=Westglen Park.

Documentation on tags can be found on the TagInfo resource website.


Your account’s API key. You can create an API key by registering for an account and copy and paste it from your account dashboard.


The center of the circle as a coordinate. Features falling inside the circle will be downloaded.

The center coordinate is formatted as longitude,latitude. One of center or address is required.


The center of the circle as an address. Features falling inside the circle will be downloaded.

If the address is ambiguous, the best result will be chosen, which may or may not be the target address. To get the best results, provide the full address, including: building number, street name, city name, state, zip code, and country.

An example address is 335 McAllister St, San Francisco, CA 94102. One of center or address is required.

Providing an address requires the growth plan because it consumes third-party geocoding resources.

The radius around the center, in meters. Maximum radius is 16,093 meters (10 miles).


This optional parameter, when passed, simplifies the output geometries. The only valid value is simplify=point, which turns every output geometry into a single point (its centroid).

This is convenient for approximating LineStrings and MultiPolygons as their central point.

Note the centroid may fall outside the original polygon, e.g. a donut’s centroid is outside the ring.


When the OSM feature extract is successfully created, a 200 OK response will be issued, with Content-Type: application/json. The body will be a valid GeoJSON FeatureCollection.

In the event of an error, an error response will be issued, usually with a 5xx error code. The error will be JSON-formatted, with an error field describing the cause.


The error message if the extract request parameters were incorrectly formatted.

This response field will not be present if the extract succeeds.
