openstates_search_billsSearch state legislative bills across all covered US jurisdictions. Supports full-text search, jurisdiction/session filtering, subject tags, sponsor lookups, and sort order.

openstates_get_billFetch 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 se…
