Api Endpoint

2s

Resolve a US street address to its congressional district (119th Congress), state, and county, via the US Census Bureau geocoder. Returns the matched/normalized address, latitude/longitude, state (name + 2-letter abbreviation), county, and the district number within the state (null for at-large or non-voting delegate districts). The point-in-polygon district lookup is something an agent can't do from a sandbox. Pair it with the gov/congress.* endpoints to find the representatives once you have the state + district. Public domain, keyless.
