Reverse Geocoding APIs
Reverse geocoding turns a latitude and longitude into a readable place: a street, city, postcode or admin region. BigDataCloud's Free API does it client-side with no key, and its paid sibling returns localities in more than 100 languages. AtlasFetch adds ISO codes for country and region, and GeoDataSource returns the nearest city with timezone and currency. Yandex.Maps Geocoder covers Russia, the CIS, Turkey and Israel on paid tiers only.

Choosing a Reverse Geocoding API
Is there a free Reverse Geocoding API?
Yes. BigDataCloud's Free API, Nominatim and API Adresse are free to use, and OpenCage, AtlasFetch, BigDataCloud's Reverse Geocoding API, Geoapify, Geocode.xyz and 12 others have a free tier alongside paid plans.
Which Reverse Geocoding APIs work without an API key?
BigDataCloud's Free API, Nominatim, API Adresse, Geocode.xyz and GeoDescription need no key or sign-up, so you can try them with a plain request.
Can I call a Reverse Geocoding API from front-end JavaScript?
BigDataCloud's Free API, Nominatim, API Adresse and Geocode.xyz allow cross-origin requests and need no key, so they work straight from the browser. For the others, call them from your server so your key stays private.
Can I use Reverse Geocoding APIs in a commercial project?
BigDataCloud's Free API, API Adresse, AtlasFetch, Geoapify, Geocode.xyz and 9 others permit commercial use. Nominatim, OpenCage, GeoDescription and positionstack restrict it, for example to non-commercial or attributed use, so read the terms first.
Which Reverse Geocoding APIs work with AI agents?
AtlasFetch and LatLng have an MCP server, so an AI agent can call them directly. OpenCage, Geocodio, GeoDataSource and Mapbase publish an OpenAPI spec for generating clients and tools.
