How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
A JSON object containing the postal code (cp), city label (label), and city name (ville) corresponding to the queried coordinates. Example: {"cp": "97110", "label": "Pointe-à-Pitre", "ville": "Pointe-à-Pitre"}.
Example use cases
Geotagging photos with location names
“I have GPS coordinates from my camera — latitude 16.24, longitude -61.53 — can you tell me the city name and postal code for that location so I can tag my photo?”
Enriching delivery address from GPS
“Our delivery driver's GPS logged coordinates 48.8566, 2.3522 — what city and zip code is that so I can fill in the address field?”
Identifying user location in analytics
“A user session recorded coordinates 45.75, 4.85 — what city and postal code does that correspond to, so I can categorize them by region?”
Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/fr/reverse-geocodeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call reverse geocoding lookup without signing up for an account or managing API keys — ideal for AI agents making occasional or bursty geocoding calls that pay per use in USDC via the x402 protocol. Prefer this over subscription-based geocoding APIs when you want zero-commitment usage and the x402 micropayment flow is already integrated into your agent runtime.
Side effects
- Missing or invalid query parameters (lat/lon not provided) — likely returns a 400 or error JSON
- Coordinates outside supported geographic coverage — may return empty or null fields
- Payment not fulfilled via x402 — returns HTTP 402 Payment Required
- Network timeout or cold-start on serverless deployment — request times out
