3 The lookup API allows to query the address and other details of one or
4 multiple OSM objects like node, way or relation.
8 The lookup API has the following format:
11 https://nominatim.openstreetmap.org/lookup?osm_ids=[N|W|R]<value>,…,…,&<params>
14 `osm_ids` is mandatory and must contain a comma-separated list of OSM ids each
15 prefixed with its type, one of node(N), way(W) or relation(R). Up to 50 ids
16 can be queried at the same time.
18 !!! danger "Deprecation warning"
19 The API can also be used with the URL
20 `https://nominatim.openstreetmap.org/lookup.php`. This is now deprecated
21 and will be removed in future versions.
26 This section lists additional optional parameters.
30 | Parameter | Value | Default |
31 |-----------| ----- | ------- |
32 | format | one of: `xml`, `json`, `jsonv2`, `geojson`, `geocodejson` | `jsonv2` |
34 See [Place Output Formats](Output.md) for details on each format.
37 | Parameter | Value | Default |
38 |-----------| ----- | ------- |
39 | json_callback | function name | _unset_ |
41 When given, then JSON output will be wrapped in a callback function with
42 the given name. See [JSONP](https://en.wikipedia.org/wiki/JSONP) for more
45 Only has an effect for JSON output formats.
50 | Parameter | Value | Default |
51 |-----------| ----- | ------- |
52 | addressdetails | 0 or 1 | 0 |
54 When set to 1, include a breakdown of the address into elements.
55 The exact content of the address breakdown depends on the output format.
58 If you are interested in a stable classification of address categories
59 (suburb, city, state, etc), have a look at the `geocodejson` format.
60 All other formats return classifications according to OSM tagging.
61 There is a much larger set of categories and they are not always consistent,
62 which makes them very hard to work with.
65 | Parameter | Value | Default |
66 |-----------| ----- | ------- |
67 | extratags | 0 or 1 | 0 |
69 When set to 1, the response include any additional information in the result
70 that is available in the database, e.g. wikipedia link, opening hours.
73 | Parameter | Value | Default |
74 |-----------| ----- | ------- |
75 | namedetails | 0 or 1 | 0 |
77 When set to 1, include a full list of names for the result. These may include
78 language variants, older names, references and brand.
81 ### Language of results
83 | Parameter | Value | Default |
84 |-----------| ----- | ------- |
85 | accept-language | browser language string | content of "Accept-Language" HTTP header |
87 Preferred language order for showing search results. This may either be
88 a simple comma-separated list of language codes or have the same format
89 as the ["Accept-Language" HTTP header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language).
92 First-time users of Nominatim tend to be confused that they get different
93 results when using Nominatim in the browser versus in a command-line tool
94 like wget or curl. The command-line tools
95 usually don't send any Accept-Language header, prompting Nominatim
96 to show results in the local language. Browsers on the contratry always
97 send the currently chosen browser language.
102 | Parameter | Value | Default |
103 |-----------| ----- | ------- |
104 | polygon_geojson | 0 or 1 | 0 |
105 | polygon_kml | 0 or 1 | 0 |
106 | polygon_svg | 0 or 1 | 0 |
107 | polygon_text | 0 or 1 | 0 |
109 Add the full geometry of the place to the result output. Output formats
110 in GeoJSON, KML, SVG or WKT are supported. Only one of these
111 options can be used at a time.
113 | Parameter | Value | Default |
114 |-----------| ----- | ------- |
115 | polygon_threshold | floating-point number | 0.0 |
117 When one of the polygon_* outputs is chosen, return a simplified version
118 of the output geometry. The parameter describes the
119 tolerance in degrees with which the geometry may differ from the original
120 geometry. Topology is preserved in the geometry.
125 | Parameter | Value | Default |
126 |-----------| ----- | ------- |
127 | email | valid email address | _unset_ |
129 If you are making large numbers of request please include an appropriate email
130 address to identify your requests. See Nominatim's
131 [Usage Policy](https://operations.osmfoundation.org/policies/nominatim/) for more details.
134 | Parameter | Value | Default |
135 |-----------| ----- | ------- |
136 | debug | 0 or 1 | 0 |
138 Output assorted developer debug information. Data on internals of Nominatim's
139 "search loop" logic, and SQL queries. The output is HTML format.
140 This overrides the specified machine readable format.
