census_block
Pack: fcc · Endpoint: https://gateway.pipeworx.io/fcc/mcp
Resolve a US latitude/longitude (decimal degrees) to its Census block, county, and state FIPS codes and names. Returns the 15-digit block FIPS, 5-digit county FIPS, 2-digit state FIPS, state code/name, and a bounding box. Pairs with the US Census API (FIPS codes are its join keys). Coordinates outside the US yield null FIPS values.
