How this service works
Pay-per-call (x402/USDC on Base) market-data, geocoding, randomness and hook-risk endpoints. Free demo route included.
Output
Returns the display name (full human-readable address string), structured address fields (road, city, state, postcode, country), plus place type and category. Returns 404 for ocean coordinates or unmapped areas — never fabricates an address.
Example use cases
Delivery tracking address display
“I have a delivery driver's GPS position at latitude 37.7749, longitude -122.4194 — can you tell me the street address there so I can show it on the tracking dashboard?”
Geofence entry alert labeling
“My IoT device just entered a geofence at coordinates 51.5074 north, -0.1278 west — what's the human-readable address or place name at that location so I can label the alert?”
Photo location tagging
“This photo has EXIF coordinates of latitude 35.6762 and longitude 139.6503 — what street address or neighborhood does that correspond to so I can tag it properly?”
Technical details
Endpoint
POSThttps://x402.donnyautomation.com/reverse-geocode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, worldwide reverse geocode with no risk of hallucinated addresses — it explicitly returns 404 rather than fabricating a result. Ideal for AI agents in logistics, delivery tracking, geofencing, and mapping that need trustworthy structured address data. At $0.01 USDC per call it is cost-effective for moderate-volume use cases.
Side effects
- Coordinates in ocean or unmapped area return 404 with no fabricated fallback
- Invalid latitude (outside -90..90) or longitude (outside -180..180) returns an error
- Missing lat or lon query parameter results in a validation error
- Very remote or sparse areas may return only partial address fields (e.g. country only)
