Every official. Every level. One API.
One address in, the complete slate out — U.S. Congress, governors and state legislators, county commissions, mayors and ward-matched city councils, school boards, even university regents. Every field carries its source URL, verification date, and confidence.

Try it: one address, the complete slate.
Legacy providers stop at Congress and the statehouse. WardAtlas keeps going: the county commissioner for the exact board district, both council members for the right ward, all seven school-board trustees, the university regents — because local government is where advocacy actually lands.
Live against the production API, no key needed. Try any U.S. address — outside the activated areas you'll see the nationwide federal + state layer.
Local & board coverage
Townships, city councils with ward matching, county commissions, school and university boards — the layer no legacy API carries.
Committee memberships
Chairs, vice-chairs, and ranking members for Congress and state legislatures — the highest-value targeting signal in advocacy.
Machine-checked contact forms
Congress publishes no email. Our contact-form URLs are liveness-checked nightly, so campaigns never dead-end.
Per-field provenance
Every phone, email, and bio carries its source URL, verification timestamp, and confidence score. Trust, inspectable.
Built for rosters, priced for rosters.
Flat-cost bulk endpoints (/v1/officials?state=MI) instead of per-lookup credit burn, weak ETags and a
changed_since feed so your cache learns about elections before your users do, and temporal queries
(valid_on) across redistricting vintages.

Need your jurisdiction? We'll activate it.
The atlas grows on demand. A jurisdiction activation covers everything we did for our pilot county: we curate the official rosters, load the sub-county district boundaries (commission districts, wards), run the first collection with human verification of every field, and fold the jurisdiction into the automated monthly refresh and nightly liveness checks — typically live within days.
1 · Curate
Official sources identified for every elected body — county board, municipalities, school districts, special boards.
2 · Verify
First collection reviewed by a human, field by field, with verbatim source citations attached to every value.
3 · Maintain
Monthly automated refresh, nightly contact checks, election-season vigilance — the data stays alive after launch.
