Dataset ID

--cursor: optional string

Cursor for pagination

--format: optional string

Response format: json (default), geojson, csv, ndjson

--limit: optional number

Maximum results

--output-buffer: optional number

Buffer geometry by meters

--output-sort: optional string

Sort by: distance, name, osm_id

ReturnsExpand Collapse
feature_collection: object { features, type }

GeoJSON FeatureCollection (RFC 7946). For paginated endpoints, metadata is returned in HTTP response headers rather than the body:

Header Description
X-Limit Requested result limit
X-Has-More true if more results exist
X-Next-Cursor Opaque cursor for next page (cursor pagination)
X-Next-Offset Numeric offset for next page (offset pagination)
Link RFC 8288 rel="next" link to the next page

Content-Type is application/geo+json.

features: array of GeoJsonFeature { geometry, properties, type, id }

Array of GeoJSON Feature objects

geometry: object { coordinates, type }

GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

coordinates: array of number or array of array of number or array of array of array of number or array of array of array of array of number

Coordinates array. Nesting depth varies by geometry type: Point = [lng, lat], LineString = [[lng, lat], ...], Polygon = [[[lng, lat], ...], ...], etc.

Point: array of number

[longitude, latitude] or [longitude, latitude, elevation]

LineString or MultiPoint: array of array of number

Array of [lng, lat] positions

Polygon or MultiLineString: array of array of array of number

Array of linear rings / line strings

MultiPolygon: array of array of array of array of number

Array of polygons

type: "Point" or "LineString" or "Polygon" or 3 more

Geometry type

"Point"
"LineString"
"Polygon"
"MultiPoint"
"MultiLineString"
"MultiPolygon"
properties: map[unknown]

OSM tags flattened as key-value pairs, plus @type (node/way/relation) and @id (OSM ID) metadata fields. May include distance_m for proximity queries.

type: "Feature"

Always Feature

"Feature"
id: optional string

Compound identifier in type/osm_id format

type: "FeatureCollection"

Always FeatureCollection

"FeatureCollection"
