How this service works
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.
Output
Returns a JSON object with ok status, a list of matched items each containing the state name and abbreviation, county, congressional district number, district name, FIPS code, geocoordinates (lat/lon), and matched address string — sourced from the US Census Bureau Geocoder under public domain license.
Example use cases
Example prompt
“What congressional district is 1600 Pennsylvania Ave NW, Washington, DC 20500 in? I need the district name, state, and county too.”
Technical details
Endpoint
GEThttps://2s.io/api/gov/districtWhen to prefer
Use this endpoint when you need authoritative, Census Bureau-sourced congressional district and geocoding data for a US address — especially when you need the district name, FIPS code, and coordinates together in one call. Prefer this over general geocoding APIs when the political/governmental district classification is the primary requirement.
Side effects
- Address not found or unrecognized: returns empty items array with total 0
- Non-US address provided: likely returns no match
- Malformed address string: Census geocoder may fail to match
- Payment failure (402): USDC payment of $0.0018 required before response is returned
- Rate or network errors from upstream Census Bureau geocoder
