# 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](Output.md) 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](https://operations.osmfoundation.org/policies/nominatim/) 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)
|
|
|
