# Overpass API

Canonical: https://gisforweb.com/tools/overpass-api/

Query engine that runs Overpass QL against the OpenStreetMap database over HTTP.

Overpass API is a read-only database engine that answers queries against the OpenStreetMap data set using the Overpass QL language. Results are returned as JSON, XML, GeoJSON, CSV or KML, which makes it the usual way for an application to fetch a small or medium OSM extract at runtime. Instances are self-hosted from a planet or regional extract, or queried against the public server at overpass-api.de.
