How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

Output

Returns a JSON object containing an array of address matches, each with latitude/longitude coordinates, a standardized matched address string, and address components (city, state, ZIP). Also includes metadata: provider attribution, benchmark used, coverage note, privacy statement, and whether an upstream error occurred. Uses Census address-range interpolation so coordinates may not be rooftop-precise.

Example use cases

Enrich delivery addresses with coordinates

“I have a list of customer shipping addresses in the US — can you geocode '350 Fifth Avenue, New York, NY 10118' to get its latitude and longitude so I can plot it on a map?”

Validate and pin a business location

“Can you look up the coordinates for '1 Apple Park Way, Cupertino, CA 95014' and tell me the matched address and ZIP code?”

Locate a property for a real-estate tool

“I need the lat/lon for '233 S Wacker Dr, Chicago, IL 60606' — use the current public benchmark and give me back the geographic coordinates.”

When to prefer

Choose this endpoint when you need a free, no-signup, pay-per-result geocoder for U.S., Puerto Rico, or U.S. Island Areas addresses and want verifiable, Census-backed coordinates billed in USDC micro-payments. It is ideal for agent workflows that need lightweight address-to-coordinate resolution without API key management, especially when Census interpolated accuracy (not rooftop precision) is sufficient. Prefer alternatives when you need global address coverage, rooftop-precise coordinates, or reverse geocoding.

Side effects

Address not found — match_count is 0 and matches array is empty
Upstream Census Bureau API error — upstream_error: true with no matches
Invalid or non-US address input — may return zero matches or error
Timeout exceeded if Census geocoder is slow — configurable between 2–8 seconds
Malformed input (address too short or too long) — schema validation error
