build_legislative_evidence_packet

Returns a `how_to_cite` block with a one-line `cite_as` sentence, a human `permalink`, a JSON `download_url`, and a `snapshot_id` that changes if and only if a cited fact about the bill changes -- so a reader can check later whether the citation still holds. Snapshots are NOT archived; the id is a change detector, not a way to retrieve an older packet. Pass `question` to record what the packet was assembled to answer; it is echoed into the artifact so a filed packet carries its own scope.
compare_bill_versions
bill_id*version_id_aversion_id_b
Deterministic diff (unified + structured) between two versions of a bill's extracted text. Defaults to earliest vs. latest texted version if version ids are omitted. Errors… Deterministic diff (unified + structured) between two versions of a bill's extracted text. Defaults to earliest vs. latest texted version if version ids are omitted. Errors if fewer than 2 versions have extracted text. Result is labeled 'derived' (computed by Bill Commons, not an official document).

Look up by canonical bill_id (UUID), or by jurisdiction + identifier (+ optional session to disambiguate).
get_jurisdiction_coverage
state
Return the jurisdiction_coverage state-machine status for one state (abbreviation or name), or the full 51-jurisdiction coverage matrix if state is omitted. Return the jurisdiction_coverage state-machine status for one state (abbreviation or name), or the full 51-jurisdiction coverage matrix if state is omitted.
get_upcoming_hearings

Fetch vote event(s) with member-level (yes/no/other/absent) vote records. Provide vote_event_id for one vote, or bill_id for all recorded votes on that bill.

Each topic is a title/subject membership rule tuned for precision over recall, with a live bill_count and how_to_fetch_bills. This tool does not itself return bill rows -- pair it with search_legislation or the REST API's /topics/{slug} for the bills.

Optionally filter by jurisdiction (two-letter state code or name), chamber, and status. For a curated cross-state slice of a subject (e.g. "every AI bill in the country") rather than an ad-hoc keyword search, call list_topics first -- its membership rules also match on structured subject tags this full-text search does not see.
