How this service works
Reverse geocoding — latitude/longitude → nearest formatted address plus structured components (houseNumber, road, suburb, city, county, state, postcode, country, countryCode). Query: lat (-90..90), lon (-180..180). Underlying data is OpenStreetMap (ODbL). Sister: /api/geocode/address.
Output
Returns the nearest formatted street address plus structured components including houseNumber, road, suburb, city, county, state, postcode, country, and countryCode for the given latitude/longitude coordinate.
Example use cases
Example prompt
“What's the nearest street address for the coordinates 40.7128, -74.0060? I need the full address broken down into house number, road, city, state, and zip code.”
Technical details
Endpoint
GEThttps://2s.io/api/geocode/reverseWhen to prefer
Use this endpoint when you need to convert raw GPS or map coordinates into a human-readable address or structured postal components. Ideal for enriching location data in pipelines, labeling map pins, or resolving device GPS output into actionable addresses. Prefer over forward geocoding when you already have coordinates and need the address, not vice versa.
Side effects
- Coordinates out of range (-90..90 for lat, -180..180 for lon) return a 400 error
- Remote or ocean coordinates may return no address if no OSM data exists nearby
- Missing required lat or lon parameter returns a 400 validation error
- Payment not provided or insufficient returns a 402 Payment Required
- OpenStreetMap data may be outdated or incomplete for rural/newly developed areas
