How this service works
817 pay-per-call APIs for AI agents. Every endpoint is POST /<name> and is payable in USDC over x402 on Base and Solana — no signup, no API key, just pay-per-call. GET https://x402.agentutility.ai/ returns the same catalog as machine-readable JSON.
Output
A JSON object containing the resolved address broken into structured fields (road, city, county, state, country, postcode, country_code), plus a full display_name string, place type, OSM ID, place_id, importance score, zoom level, and a bounding box array for the resolved place. The source attribution to OpenStreetMap Nominatim is included.
Example use cases
Geotagged photo address lookup
“I have a photo with GPS metadata at latitude 48.8584 and longitude 2.2945 — can you tell me the full street address and neighborhood for those coordinates?”
Delivery location verification
“A driver just sent me their current GPS position: 40.7128 latitude, -74.0060 longitude. What's the actual street address there so I can confirm it matches the delivery destination?”
Field survey report enrichment
“I recorded a site observation at coordinates 51.5074, -0.1278 — what's the full postal address including road name, city, and postcode so I can include it in the report?”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/reverse-geocode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a GPS coordinate pair and need a human-readable address or structured location metadata without setting up a Google Maps or HERE API account. It is pay-per-call with no signup, making it ideal for occasional or agent-driven reverse geocoding tasks. Prefer it over forward geocoding endpoints when you already have coordinates and need place details. The zoom parameter makes it flexible for coarse (country/state) or fine (street/building) resolution.
Side effects
- Coordinates out of range (-90 to 90 for latitude, -180 to 180 for longitude) will result in an error
- Remote ocean or uninhabited areas may return no meaningful address, only country-level data
- Missing required latitude or longitude fields returns a validation error
- Very high zoom levels in sparse areas may fall back to coarser resolution results
- x402 payment failure or insufficient USDC balance blocks the call
