How this service works
Turn an address into coordinates: BAN for France (INSEE code, score), OpenStreetMap elsewhere. Address to coordinates: for France the official BAN registry (house number, street, postcode, city, INSEE code, match score), elsewhere OpenStreetMap Nominatim. Query: ?q=8 rue de la Paix Paris&country=fr&limit=1
Output
Returns one or more geocoded results containing latitude and longitude coordinates. For French addresses (country=fr), includes BAN-specific fields: house number, street name, postcode, city, INSEE municipality code, and a confidence/match score. For other countries, returns OpenStreetMap Nominatim results with coordinates and place metadata.
Example use cases
Geocode French delivery address
“I have a delivery address — 14 avenue des Champs-Élysées, 75008 Paris — can you get me the exact lat/lon and the INSEE code using the official French BAN registry?”
Map user-submitted form addresses
“A customer just submitted their address as '3 place du Capitole, Toulouse, France' — can you resolve that to coordinates so I can pin it on a map?”
Geocode international address via OpenStreetMap
“I need the coordinates for '221B Baker Street, London, UK' — can you forward geocode that address for me?”

Endpoint
GEThttps://api.x-402.online/v1/geo/forward?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need official French address geocoding with INSEE codes and confidence scores (sourced from the authoritative BAN registry), or when you need a unified geocoding endpoint that handles both French and international addresses. It is well-suited for AI agents requiring pay-per-call geocoding without account setup, billed per query via USDC on Base.
Side effects
- Ambiguous address string returns low-confidence or incorrect match
- Address not found in BAN or Nominatim returns empty results array
- Invalid country code parameter may fall back to wrong data source
- Rate limiting or payment failure returns HTTP 402 error
- Malformed query string returns 400 bad request
