French Reverse Geocoder (lat/lon to address)

Use this endpoint when you need to resolve GPS coordinates to a human-readable French address, especially when coverage of French overseas territories (Guadeloupe, Martinique, Réunion, etc.) is required. Prefer this over generic geocoding APIs when operating within the French administrative address system.

• Coordinates outside France or overseas territories return no result or an error
• Missing lat or lon query parameter returns a 400 bad request
• Coordinates in the ocean or unpopulated areas may return no matching address
• Payment not completed results in a 402 Payment Required response
