How this service works
Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).
Output
A JSON object containing human-readable location information for the provided coordinates, typically including country, region/state, city, and possibly administrative subdivision details derived from the lat/lon pair.
Example use cases
Tagging user location from GPS
“I have a user's GPS coordinates — latitude 40.7128, longitude -74.0060 — can you tell me what city and country that is so I can display it in their profile?”
Enriching IoT device telemetry
“Our sensor reported coordinates 35.6762 lat and 139.6503 lon — what city and region is that device located in?”
Verifying delivery address region
“A package was scanned at 51.5074 latitude and -0.1278 longitude — what city and country does that put it in?”

Endpoint
GEThttps://worlddata402.worlddata402.workers.dev/v1/reverse-geocode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription reverse geocoding service that settles instantly via USDC on Base mainnet through the x402 protocol, making it ideal for AI agents with autonomous crypto payment capabilities. Best suited for sporadic or agent-driven lookups where a monthly SaaS subscription would be wasteful.
Side effects
- Missing required lat or lon parameter returns a 400 error
- Coordinates outside valid range (lat: -90 to 90, lon: -180 to 180) may return an error or empty result
- Payment failure via x402/USDC returns a 402 Payment Required response
- Coordinates in the middle of an ocean or uninhabited area may return sparse or null location fields
- Rate limits or worker errors may return 5xx responses
