## Tools (as reported by the server, not verified)

- `openstates\_search\_bills`: Search state legislative bills across all covered US jurisdictions. Supports full-text search, jurisdiction/session filtering, subject tags, sponsor lookups, and sort order. Either jurisdiction or q \(full-text\) is required, and pairing them is the reliable form — a q-only search spans all 56 jurisdi
- `openstates\_get\_bill`: Fetch full detail for a specific state bill. Accepts either the three-part path \(jurisdiction + session + bill\_id\) or a direct OCD bill ID \(openstates\_id from search results\). Use include to request votes, actions, sponsorships, documents, and versions in one call rather than searching again. includ
- `openstates\_search\_people`: Search state legislators and officials by name, jurisdiction, chamber, or district, or fetch specific people by OCD person ID. Party is reported on every result but cannot be filtered on — narrow by party after the call. Either jurisdiction or id is required — a search spanning all 56 jurisdictions
- `openstates\_get\_legislators\_by\_location`: Find every legislator representing a geographic coordinate — both tiers. Pass latitude and longitude to get the state senators and representatives for that location \(and potentially governor/executive officials\), plus the coordinate's two US Senators and its US Representative. jurisdiction.classific
- `openstates\_search\_committees`: List committees for a jurisdiction. jurisdiction is required — a request spanning all 56 jurisdictions exceeds the upstream timeout, so scope every call to a single state; use openstates\_list\_jurisdictions to pick one. Experimental — Open States is actively working to restore committee support and n
- `openstates\_get\_committee`: Fetch committee detail by OCD organization ID. Returns name, classification, and membership roster when include=memberships is requested. Experimental — not all states have committee data in Open States. Obtain the committee\_id from openstates\_search\_committees.
- `openstates\_search\_events`: Search hearings, floor sessions, and committee meetings. jurisdiction is required — the Open States events endpoint has no all-states search, so scope every call to a single state; use openstates\_list\_jurisdictions to pick one. Experimental — most states do not publish event data to Open States. Use
- `openstates\_get\_event`: Fetch full event detail by OCD event ID. Returns agenda, participants, media links, and associated documents when requested via include. Experimental — event coverage is limited in Open States. Obtain the event\_id from openstates\_search\_events.
- `openstates\_list\_jurisdictions`: List all jurisdictions covered by Open States — all 50 states, DC, and 5 US territories \(American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the US Virgin Islands\): 56 in total, returned complete in a single default call. Returns coverage metadata: latest bill update time, latest people
- `openstates\_get\_jurisdiction`: Fetch full metadata for a specific jurisdiction including all legislative sessions, their identifiers, and coverage dates. Use when you need to know the exact session identifier for a state before filtering bill searches — session formats vary widely \(e.g., "2025", "2025rs", "2025s1"\). Jurisdiction
