Technical details
Endpoint
GEThttps://geo-us.x402tookit.com/political-districts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify the specific political districts (congressional, state senate, state house) associated with a US street address. Prefer it over generic geocoding endpoints when the goal is civic or political context rather than coordinates, and over census geography endpoints when district codes rather than census tracts are needed.
Side effects
- Address not found or unresolvable — returns null districts with reasons array explaining the failure
- Non-US address provided — likely returns error or null results
- Ambiguous address matched to multiple locations — may return degraded flag with best-guess match
- Missing required address query parameter — request rejected
- Address in US territory without full congressional representation (e.g. DC) — may return partial or null congressional district
