Free French Geographical Data API for Geocoding & Reverse Geocoding

Overview

GeoApi offers RESTful endpoints for French geographical data, including geocoding (address-to-coordinates), reverse geocoding (coordinates-to-address), and access to administrative divisions (regions, departments, communes). Responses are JSON-formatted. Key endpoints: /search (geocode addresses), /reverse (retrieve location from coords), /communes (list communes with details like population or postal codes). Use cases: French mapping apps, logistics tools, local service platforms, or analytics requiring accurate French location data. It supports filtering by administrative level and returns metadata like boundary coordinates and official codes.
