How this service works
Address geocoding API for agents: geocode one U.S., Puerto Rico, or U.S. Island Areas address for $0.001 USDC through the public Census Geocoder. Returns approximate coordinates with required Census attribution—no global maps, navigation, or address retention.
Output
Returns approximate latitude and longitude coordinates for the submitted address along with the matched address string and required U.S. Census Bureau attribution. Does not store addresses or support navigation routing.
Example use cases
Enrich delivery address with coordinates
“I have a shipping address — 742 Evergreen Terrace, Springfield, IL 62704 — can you look up its coordinates so I can plot it on a map?”
Verify and pin a business location
“What are the latitude and longitude coordinates for 350 Fifth Avenue, New York, NY 10118? I need to geocode it using the current Census benchmark.”
Geocode a Puerto Rico address
“Can you find the coordinates for Calle Fortaleza 151, San Juan, PR 00901? I need the lat/lon for a US territories address.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/geocode-us?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need low-cost ($0.001 USDC), single-address geocoding strictly within the United States, Puerto Rico, or U.S. Island Areas and can accept approximate coordinates with Census attribution. Prefer this over commercial geocoding APIs when cost sensitivity is high, global coverage is not needed, and address retention is not required.
Side effects
- Address not found or ambiguous — Census Geocoder returns no match
- Timeout exceeded (max 8 seconds) — returns timeout error
- Non-US address submitted — not supported, returns error
- Malformed address string — returns validation error
- Census Geocoder upstream unavailable — returns service error
