`get_candidate_photo`The URL of a candidate's official portrait (GET /v1/photos/{candidate_id} returns the image bytes). Sources are official state-legislature and congressional portraits, public-domain and licensed images only — never a third party's photo library — and each carries a license and attribution string that MUST be shown when the license requires it (Wikimedia CC BY). Returns null when the candidate has no accepted portrait — which is the COMMON case: only about a tenth of the 2026 field has one (11%), so design for an initials-avatar default.

`get_coverage`Per-state depth snapshot (GET /v1/coverage): how COMPLETE each jurisdiction's data is — bill counts, the share of bills holding at least one vote, text or sponsor, and whether the legislature is currently in session. Use it before drawing conclusions from a thin result set, to tell 'no such bills' apart from 'this state is thinly covered'. Read the completeness ratios rather than the raw percentages: most bills die in committee without ever getting a roll call, so a low pct_with_votes usually reflects the legislature, not a gap in the data. Served from a materialised snapshot; `computed_at` gives its age.

Get session_id from list_sessions.	No	Yes	Not declared	Yes
`list_sessions`Legislative sessions (GET /v1/sessions): regular and special sessions with their years, start/sine-die dates and a session_id. Use this to resolve which session a bill belongs to, to find the current session for a state, or to pass session_id as a filter to search_bills. Omit `state` to list every jurisdiction's sessions.

`list_states`The jurisdiction directory (GET /v1/states): the 50 states, D.C. and the U.S. Congress with their state_id, 2-letter code and full name. Returns the full list (52 rows) so you can resolve a name to a code or enumerate everything the corpus covers. For how COMPLETE each jurisdiction's data is, use get_coverage instead.

`list_statute_coverage`Which jurisdictions' codified law is loaded, and how big and current it is (GET /v1/statutes/coverage): per state the number of codes, sections, bill links and the edition it is current through. Pass state to list that state's codes (GET /v1/statutes/codes) — the code_id values used by get_statute lookups. Call this first to know whether a state's statutes are available.

No	Yes	Not declared	Yes
`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 gauge what a jurisdiction is legislating on. Scope with `state` and narrow with `q`.

`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 the topic's actual bills, use search_bills with topic=<slug>.

`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 plus pagination; call get_bill for the full record. Corpus is 2026-forward only. status_id values: 1=Introduced, 2=In Committee, 3=Passed One Chamber, 4=Passed Both Chambers (for a simple resolution, bill_type_id 2: Adopted, its final step), 5=Signed into Law, 6=Vetoed, 7=Failed/Dead, 8=Chaptered.

`search_statutes`Full-text search of a state's codified law (GET /v1/statutes/search). Use for 'what does the law say about X' and to find the section a bill or ballot measure changes. Returns matching sections with headings and excerpts; fetch the whole section with get_statute. Only states whose code is loaded resolve to section text (see list_statute_coverage); a link to a section we hold carries resolved:true and the text, otherwise just the citation as written.
