-## Address lookup
+# Address lookup
-Lookup the address of one or multiple OSM objects like node, way or relation.
+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:
-### Parameters
```
- https://nominatim.openstreetmap.org/lookup?<query>
+ https://nominatim.openstreetmap.org/lookup?osm_ids=[N|W|R]<value>,…,…,&<params>
```
-* `format=[xml|json]`
+`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
- * Output format
+* `format=[xml|json|jsonv2|geojson|geocodejson]`
+
+See [Place Output Formats](Output.md) for details on each format. (Default: xml)
* `json_callback=<string>`
- * Wrap json output in a callback function (JSONP) i.e. `<string>(<json>)`
+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 uses standard rfc2616 accept-language string or a simple comma separated list of language codes.

-* `osm_ids=[N|W|R]<value>,…,[N|W|R]<value`
- * A list of up to 50 specific osm node, way or relations ids to return the addresses for
+### Polygon output
-* `addressdetails=[0|1]`
- * defaults to 0
- * Include a breakdown of the address into elements
+* `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 a valid email address or alternatively include your email address as part of the User-Agent string.

+
+* `debug=[0|1]`
-* `extratags=1`
- * Include additional information in the result if available, e.g. wikipedia link, opening hours.
+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)
-* `namedetails=1`
- * Include a list of alternative names in the results.
- * These may include language variants, references, operator and brand.
