Address lookup

The lookup API allows to query the address and other details of one or multiple OSM objects like node, way or relation.

Parameters

The lookup API has the following format:

  https://nominatim.openstreetmap.org/lookup?osm_ids=[N|W|R]<value>,…,…,&<params>

osm_ids is mandatory and must contain a comma-separated list of OSM ids each prefixed with its type, one of node(N), way(W) or relation(R). Up to 50 ids can be queried at the same time.

Additional optional parameters are explained below.

Output format

format=[xml|json|jsonv2|geojson|geocodejson]

See Place Output Formats for details on each format. (Default: xml)

json_callback=<string>

Wrap JSON output in a callback function (JSONP) i.e. <string>(<json>). Only has an effect for JSON output formats.

Output details

addressdetails=[0|1]

Include a breakdown of the address into elements. (Default: 0)

extratags=[0|1]

Include additional information in the result if available, e.g. wikipedia link, opening hours. (Default: 0)

namedetails=[0|1]

Include a list of alternative names in the results. These may include language variants, references, operator and brand. (Default: 0)

Language of results

accept-language=<browser language string>

Preferred language order for showing search results, overrides the value specified in the "Accept-Language" HTTP header. Either use a standard RFC2616 accept-language string or a simple comma-separated list of language codes.

Polygon output

polygon_geojson=1
polygon_kml=1
polygon_svg=1
polygon_text=1

Output geometry of results as a GeoJSON, KML, SVG or WKT. Only one of these options can be used at a time. (Default: 0)

polygon_threshold=0.0

Return a simplified version of the output geometry. The parameter is the tolerance in degrees with which the geometry may differ from the original geometry. Topology is preserved in the result. (Default: 0.0)

Other

email=<valid email address>

If you are making large numbers of request please include an appropriate email address to identify your requests. See Nominatim's Usage Policy for more details.

debug=[0|1]

Output assorted developer debug information. Data on internals of Nominatim's "Search Loop" logic, and SQL queries. The output is (rough) HTML format. This overrides the specified machine readable format. (Default: 0)
