Nominatim API

Nominatim indexes named (or numbered) features within the OpenStreetMap (OSM) dataset and a subset of other unnamed features (pubs, hotels, churches, etc).

Its API has the following endpoints for querying the data:

  • /search - search OSM objects by name or type
  • /reverse - search OSM object by their location
  • /lookup - look up address details for OSM objects by their ID
  • /status - query the status of the server
  • /deletable - list objects that have been deleted in OSM but are held back in Nominatim in case the deletion was accidental
  • /polygons - list of broken polygons detected by Nominatim
  • /details - show internal details for an object (for debugging only)
