How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with the US state name and FIPS code, county name and FIPS code, and the full 15-digit FCC census block FIPS code for the queried geographic location.
Example use cases
Broadband coverage area classification
“I have a list of GPS coordinates from cell tower surveys — for each one, can you tell me which FCC census block it falls in, including the state and county FIPS codes?”
Regulatory compliance geo-tagging
“We need to tag this installation at 37.7749° N, 122.4194° W with its official state, county, and census block FIPS codes for an FCC filing.”
Real estate location enrichment
“For the property at coordinates 41.8781° N, 87.6298° W, what are the official state and county names and their FIPS codes, and which census block does it fall in?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/us-geo-fcc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative FCC census block and FIPS code lookups for US coordinates — especially for telecom regulatory filings, broadband mapping, census data enrichment, or any workflow requiring official US administrative boundary classification from a lat/lng point. Prefer this over general reverse-geocoding when the specific FCC block FIPS code is required.
Side effects
- Coordinates outside the United States return no results or an error
- Missing or malformed latitude/longitude parameters cause a 400-level error
- Coordinates on exact boundary edges may return unexpected county assignments
- Payment failure via x402 returns a 402 response before the lookup executes
