class FeatureCollection:

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: List<GeoJsonFeature>

Array of GeoJSON Feature objects

geometry: GeoJsonGeometry

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

coordinates: Coordinates

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

One of the following:

List<Double>

List<List<Double>>

List<List<List<Double>>>

List<List<List<List<Double>>>>

type: Type

Geometry type

One of the following:

POINT("Point")

LINE_STRING("LineString")

POLYGON("Polygon")

MULTI_POINT("MultiPoint")

MULTI_LINE_STRING("MultiLineString")

MULTI_POLYGON("MultiPolygon")

properties: Properties

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: Type

Always Feature

id: Optional<String>

Compound identifier in type/osm_id format
