How this service works
Verify French companies, EU VAT numbers, and addresses from one API. Pay per call with USDC on Base via x402. No account, no API key.
Output
Returns a JSON object with the matched address label, street name, house number, city, postcode, latitude, longitude, and a confidence score (0–1). Up to the requested number of matches (default 5, max 10) are returned, ranked by relevance score.
Example use cases
Address autocomplete in checkout form
“The user typed '15 rue de la paix par' into our address field — can you find the top 5 matching French addresses with their postcodes and GPS coordinates so I can show them suggestions?”
Geocoding a French delivery location
“I need the latitude and longitude for '23 Avenue des Champs' in France — can you find the best matching full address and its coordinates?”
Validating a French address before shipment
“Before we ship this order, can you verify that '8 Bd Haussmann 75009' is a real, properly formatted French address and give me the standardized label and postcode?”
Technical details
Endpoint
GEThttps://veriffr.vercel.app/api/v1/address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to autocomplete, geocode, or validate French addresses specifically, and want a pay-per-call model with no account or API key setup. It is ideal for AI agents needing lightweight, on-demand French address resolution without committing to a subscription. Prefer it over general geocoding APIs when you only need France coverage and want USDC micropayment billing on Base.
Side effects
- Query string shorter than 3 characters returns an error or empty result
- No matching addresses found returns an empty results array
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
- Invalid or malformed query parameter returns a validation error
- Network timeout from upstream address database
