search_bills | Search or list legislation with structured filters (GET /v1/bills). Use this when you know the jurisdiction, sponsor, topic, or status you want. Every filter is optional and they combine with AND. A bill number typed into q (e.g. 'HB 1', 'SB0002') matches that bill directly. Returns bill summaries p |
semantic_search_bills | Vector search over the full text of every bill (GET /v1/search/semantic): describe what you want in plain English — 'protecting kids from social media', 'limits on rent increases' — and get the closest bills with a match_score. Prefer this over search_bills for questions and topics; prefer search_bi |
get_bill | Fetch a single bill by its numeric bill_id (GET /v1/bills/{bill_id}), optionally merging in sub-resources: votes (roll calls with tallies), sponsors, history (action timeline), texts (version metadata), amendments, subjects, analyses (staff analyses), calendar (scheduled events), citations (statutes |
get_bill_diff | Compare two versions of a bill's text (GET /v1/bills/{bill_id}/diff): a unified diff plus similarity, added/removed line and character counts, and changed-section highlights. Get the two version ids from get_bill with include:['texts'] — each text row's `text_id`. Pass them as `from` (the earlier ve |
keyword_search_bills | Keyword search where EVERY term must appear (GET /v1/search/bills). Use when the user gives specific words that all have to be present, e.g. ['short-term rental', 'tax']. Prefer semantic_search_bills for questions and search_bills for structured filters. Up to 10 terms. Returns bill summaries plus p |
get_bill_text | The cleaned plain text of one bill-text version (GET /v1/texts/{text_id}), entities decoded, ready to quote or summarize. Get text_id from get_bill with include:['texts'] (each version has a date and type). Texts longer than 40,000 characters are clipped with a '[truncated]' marker. |
get_bill_text_history | Timeline of all computed diffs between successive text versions of one bill (GET /v1/bills/{bill_id}/changes): what changed, when, and how much. Use get_bill_diff for one specific pair of versions. Get bill_id from search_bills or semantic_search_bills. |
list_legislators | Search or list legislators (GET /v1/legislators) by jurisdiction, chamber, party, district, or name. This is how you turn a name into the people_id that get_legislator needs. Filters combine with AND. |
get_legislator | Fetch a legislator's profile by people_id (GET /v1/legislators/{people_id}), optionally merging in votes (every roll call they are recorded on, newest first, with their individual position: 1=Yea, 2=Nay, 3=Not Voting, 4=Absent) and bills (legislation they sponsor, with sponsor_type_id 1=primary, 2=c |
get_roll_call | Fetch a roll call by roll_call_id (GET /v1/votes/{roll_call_id}): the motion, chamber, date and yea/nay/absent tallies.

list_hearings | Scheduled committee hearings across committees (GET /v1/hearings), filterable by jurisdiction and start date. Use this to answer 'what is being heard this week' or to track when a committee next meets. For hearings on one specific committee use get_committee with include:['hearings']; for one specif |

Reason types include NewBill, StatusChange, Text, Vote and Amendment. Use this for monitoring and incremental sync — 'what move |
list_topics | The canonical topic taxonomy with per-topic bill counts (GET /v1/topics). Call this first to find the right slug for the topic filter on search_bills, instead of guessing one. Pass a slug to get that topic's detail and a sample of the raw subject names folded into it (GET /v1/topics/{slug}); to get |
list_subjects | The raw subject taxonomy with per-subject bill counts (GET /v1/subjects). Subjects are the fine-grained categories the legislatures themselves assign to bills — narrower and more numerous than the curated topic slugs from list_topics. Use this to find a subject_id to filter search_bills by, or to ga |
list_sessions | Legislative sessions (GET /v1/sessions): regular and special sessions with their years, start/sine-die dates and a session_id.

get_weekly_stage_breakdown | One row per stage with the number of bills whose latest action landed there in the window (GET /v1/bills-weekly-breakdown). All jurisdictions combined. Use for a national 'how much moved this week' number; use get_session_dashboard for one state. |
list_candidates | Search the election-candidate directory (GET /v1/candidates): people running for office. Filters combine with AND. Roughly a third carry an FEC filer id and sitting members of Congress carry a Bioguide id; both are null otherwise. Rows also carry people_id where the person has a legislative voting r |

list_districts | District metadata by state and type (GET /v1/districts): congressional, state senate, state house. Pass district_id with boundary:true to get the polygon as GeoJSON (GET /v1/districts/{id}/boundary) — it is large, so set simplify (degrees, e.g. 0.01) to shrink it. Match districts NUMERICALLY (distri |
get_candidate_photo | The URL of a candidate's official portrait (GET /v1/photos/{candidate_id} returns the image bytes).

get_usage | The current key's tier, monthly cap, requests used and remaining, and when the period resets (GET /v1/_meta/usage). Call this when a request is rate-limited (HTTP 429) or the user asks about their plan. |
manage_webhooks | Manage the key's webhook subscriptions (/v1/webhooks). action:'list' is read-only.
