How this service works
Convert addresses to coordinates or coordinates to addresses for $0.001 per request. No API key or subscription. Pay with USDC on Base via x402.
Output
A JSON object containing a 'place' field (city or locality name) and an 'address' field (full human-readable address string), e.g. {"place":"New York","address":"New York, NY, USA"}.
Example use cases
Identify delivery drop-off location
“I have a GPS coordinate from a delivery driver's log — lat 37.7749, lon -122.4194 — can you tell me what address that corresponds to?”
Annotate photo geotag with address
“My photo's EXIF data shows coordinates 51.5074, -0.1278 — what's the actual street address at that location?”
Enrich IoT sensor location data
“Our sensor reported position 48.8566, 2.3522 — what's the human-readable address or place name for those coordinates?”
Technical details
Endpoint
GEThttps://geocoding-x402.royaldemocracy.workers.dev/api/reverseWhen to prefer
Choose this endpoint when you need pay-per-use reverse geocoding with no API key or subscription required — ideal for agents that make occasional or unpredictable numbers of lookups and want to pay micro-amounts per call in USDC on Base via x402 rather than managing a monthly subscription.
Side effects
- Missing or malformed latitude/longitude query parameters returns an error
- Coordinates in remote or unmapped areas may return incomplete or null address data
- Payment not fulfilled (x402 flow incomplete) results in a 402 Payment Required response
- Invalid coordinate ranges (e.g. lat > 90) may cause lookup failure
