How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
A JSON object containing the latitude (lat), longitude (lon), and a matched canonical address string (matched) corresponding to the input address query.
Example use cases
Geocoding delivery drop-off address
“I have a delivery address — 4600 Silver Hill Rd, Washington, DC 20233 — can you look up the exact latitude and longitude so I can plot it on a map?”
Enriching a customer database with coordinates
“We have customer records with US street addresses and I need to add lat/lon coordinates to each one — can you geocode '123 Main St, Austin, TX 78701' to start?”
Pinpointing an event venue location
“I'm planning an event at 350 Fifth Avenue, New York, NY 10118 — what are the GPS coordinates for that address?”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/geo/geocodeWhen to prefer
Choose this endpoint when you need a lightweight, account-free, pay-per-call geocoder for US addresses with no API key setup required. Ideal for AI agents making occasional one-off geocoding calls where a subscription service is overkill and micropayment via USDC on Base is acceptable. Best for US addresses only.
Side effects
- Address not found or unrecognizable — may return empty or null result
- Non-US addresses are outside the supported scope
- Ambiguous address input may return an unexpected match
- Payment failure or insufficient USDC balance blocks the call
- Malformed query parameters result in a 400-level error
