api record

Bill Commons: public, open-source legislative search for all 50 US states + DC. Tools return structured JSON with canonical ids, official source_url fields, retrieved_at freshness timestamps, and explicit official-vs-derived labeling. Coverage is uneven while ingestion is in progress -- call get_jurisdiction_coverage before relying on an empty result to mean 'no such legislation exists'.

SCOPE -- what is NOT here. Do not answer these from Bill Commons, and do not report an empty result as evidence that the legislation does not exist:

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_jurisdiction_coverage unknown never probed

    Return the jurisdiction_coverage state-machine status for one state (abbreviation or name), or the full 51-jurisdiction coverage matrix if state is omitted.

  • search_legislation unknown never probed

    Search FULL BILL TEXT -- not just known-bill-number lookup. `q` is matched against titles, descriptions, AND ingested document text via Postgres websearch_to_tsquery (supports "quoted phrases", OR, and -exclusion, same syntax as a search engine), with a fuzzy pg_trgm title-similarity fallback when the exact query has no hits. `q` can ALSO be a bill number ("HB 123", "H.B. 123", "hb123" all match) and that fast path is tried first. 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.

  • get_bill_record unknown never probed

    Fetch the full record for one bill: metadata, sponsors, subjects, actions, versions, and vote-event summaries. Look up by canonical bill_id (UUID), or by jurisdiction + identifier (+ optional session to disambiguate). For a human bill number like HB 123, use jurisdiction="NC", identifier="HB 123"; bill_id is for UUIDs.

  • compare_bill_versions unknown never probed

    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).

  • build_legislative_evidence_packet unknown never probed

    Compile a citation-ready evidence packet for a bill: full official record, legislative history timeline, votes with member-level detail, and hearings -- each explicitly labeled official vs. derived with source URLs. 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.

  • list_topics unknown never probed

    List Bill Commons' curated cross-state topic trackers (e.g. artificial intelligence, youth online safety, platform accountability, cybersecurity, cryptocurrency, data privacy, local government & preemption) -- the entry point for "what subjects does Bill Commons track across all 50 states + DC" and "how do I get every bill in one". 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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/928b2b1138b1c01f/badge.svg)](https://brick.blue/agent/928b2b1138b1c01f)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
