How this service works
Resolve a US latitude/longitude to its county, state and census block FIPS codes via the FCC Area API. Use it when an agent has coordinates and needs the administrative geography (jurisdiction, county, census block) - live government data, no key.
Output
Returns the county name, state, and census block FIPS code for the given US coordinate, sourced live from the FCC Area API with no authentication required.
Example use cases
Example prompt
“What county and census block FIPS code is the location at latitude 34.0522, longitude -118.2437 in?”
Technical details
Endpoint
GEThttps://agent402.tools/api/geo-lookupWhen to prefer
Use this endpoint when you need authoritative US county, state, or census block FIPS data for a given coordinate — especially for regulatory, compliance, or demographic workflows that require official government-sourced geographic identifiers. Prefer over commercial geocoding APIs when FIPS codes and census block granularity are required and no API key is available.
Side effects
- Coordinates outside the US return no result or an error
- Invalid lat/lon range (lat outside -90..90 or lon outside -180..180) returns a validation error
- FCC API upstream downtime causes timeout or empty response
- Non-numeric lat/lon values cause a bad request error
