Reverse geocode a coordinate

client.geocode.reversePost(GeocodeReversePostParams { format, lang, lat, 5 more } params?, RequestOptionsoptions?): ReverseGeocodeResult { features, type }
POST/api/v1/geocode/reverse

Reverse geocode a coordinate

ParametersExpand Collapse
params: GeocodeReversePostParams { format, lang, lat, 5 more }
format?: string

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

lang?: string

Language code for localized names (e.g. en, de, fr)

lat?: number

Legacy shorthand. Latitude. Use near param instead.

layer?: string

Filter by layer: house or poi

limit?: number

Maximum results (default 1, max 20)

lng?: number

Legacy shorthand. Longitude. Use near param instead.

near?: string

Point geometry for reverse geocode (lat,lng or GeoJSON). Alternative to lat/lng params.

radius?: number

Search radius in meters (default 200, max 5000)

ReturnsExpand Collapse
ReverseGeocodeResult { features, type }

GeoJSON FeatureCollection of reverse geocoding results, ordered by distance from the query point. Content-Type: application/geo+json.

features: Array<GeocodingFeature { geometry, properties, type } >

Reverse geocoding results ordered by distance

geometry: GeoJsonGeometry { 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<number> | Array<Array<number>> | Array<Array<Array<number>>> | Array<Array<Array<Array<number>>>>

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

One of the following:
Array<number>
Array<Array<number>>
Array<Array<Array<number>>>
Array<Array<Array<Array<number>>>>
type: "Point" | "LineString" | "Polygon" | 3 more

Geometry type

One of the following:
"Point"
"LineString"
"Polygon"
"MultiPoint"
"MultiLineString"
"MultiPolygon"
properties: Properties { display_name, category, city, 18 more }

Geocoding result properties

display_name: string

Formatted address or place name

category?: string | null

POI category (e.g. restaurant, cafe, park). Present for place results.

city?: string | null

City or town name. Present for address results.

confidence?: number | null

Interpolation confidence (0-1). Present only for interpolated results.

maximum1
minimum0
country?: string | null

Country name. Present for reverse geocode address results.

country_code?: string | null

ISO 3166-1 alpha-2 country code

maxLength2
minLength2
distance_m?: number | null

Distance from the query point in meters (reverse geocode / nearby only)

full_address?: string | null

Complete formatted address from the database. Present for reverse geocode address results.

house_number?: string | null

House or building number. Present for address and interpolated results.

interpolated?: boolean | null

Whether this result was estimated by address interpolation rather than an exact database match.

name?: string | null

Place name (raw). Present for reverse geocode place results.

osm_id?: number | null

OpenStreetMap element ID (null for interpolated results)

osm_type?: "node" | "way" | "relation" | null

OSM element type (node, way, relation)

One of the following:
"node"
"way"
"relation"
postcode?: string | null

Postal code. Present for reverse geocode address results.

score?: number | null

Relevance score (higher is better). Incorporates text match quality, spatial proximity boost, and popularity signals. Not bounded to 0-1.

minimum0
source?: "structured" | "bm25" | "fuzzy" | 3 more | null

Result source indicating how the result was found: structured (exact field match), bm25 (full-text search), fuzzy (trigram similarity), address (reverse geocode address), place (reverse geocode POI), interpolation (estimated from neighboring addresses)

One of the following:
"structured"
"bm25"
"fuzzy"
"address"
"place"
"interpolation"
state?: string | null

State or province name. Present for reverse geocode address results.

street?: string | null

Street name. Present for address and interpolated results.

subcategory?: string | null

POI subcategory. Present for place results.

tags?: Record<string, string> | null

Raw OSM tags. Present for place results.

wikipedia?: string | null

Wikipedia article reference (e.g. en:Eiffel Tower). Present for notable places.
