Get full statute text in a selected format, optionally with a subsection tree or point-in-time reconstruction. Costs 6 credits when text is returned. Ordinary unavailable text and fetch failures are refunded. Historical available:false answers are charged when the section did not yet exist or a stored-edition date is outside held coverage; unavailable observed-change reconstructions are refunded.

Find the top USC and CFR sections that cite a statute section. Costs 2 credits; results are bounded by limit and are not pageable.

Get chapter definitions governing a statute section. Costs 4 credits; no-definition and failed lookups are refunded.

Get state session laws whose publisher affected-sections tables print this exact code section. This is not complete amendment history. Supported existing sections cost 1 credit, including empty answers; unsupported or missing sections and provider 500/503 failures are uncharged or refunded. Citation input adds the 2-credit resolution charge. Results are capped at the newest 200 with no continuation; inspect truncated and coverage.

Get metadata and source links for one US statute section by canonical section ID or resolvable citation. Costs 2 credits for an exact ID; citation input also incurs Vaquill's citation-resolution charge.

Get metadata for up to 50 statute sections in input order, with optional full text. Costs 2 credits per section returned, plus the ordinary body charge for each included body; unresolved identifiers are refunded.

Return Vaquill's authoritative live jurisdiction and corpus coverage matrix before choosing statute search filters. This discovery call costs no credits.

List sections observed as added, amended, or removed on a watched source. History is capture-bounded, retained for five years, and this call is free.

List the newest persisted webhook delivery attempts and current delivery health for a board watch. History is retained for 90 days and this bounded limit-only endpoint has no second page. Email-only watches return no attempts, and synthetic test deliveries are excluded. The read is free, but meaningful history requires a webhook or both-channel watch, which requires Vaquill Business.

List board watches owned by the connected Vaquill API-key account, including delivery destination, active state, and latest health metadata. Costs no credits.

List one oldest-first page of changes to Vaquill's state session-law registry for incremental synchronization. Costs 1 credit per page, including an empty page; validation failures are not charged and provider failures are refunded.

List one page of a state's session laws with session, date, text-availability, and instrument filters. Costs 1 credit per page. Empty pages are refunded when coverage reports a wholly partial or not-held collection; complete and partly complete jurisdiction pages are charged.

List capture-bounded observed change history for a statute section. This is not complete legislative history. Costs 1 credit per page.

List corpus sources that can be watched, including freshness, polling cadence, retrieval health, and supported scope filters. Costs no credits.

Resolve one Bluebook citation to an exact statute section. Costs 2 credits whether or not it resolves.

Resolve up to 50 unique Bluebook citations in one call from a raw list of up to 500 entries. Duplicates are collapsed, and each unique citation costs 2 credits.

Search US statutes and regulations, constitutions and court rules, executive actions and Federal Register materials, agency guidance and adjudications, sentencing guidelines, tax treaties, and session laws with semantic and keyword matching. Costs 4 credits, plus 6 credits for each full body returned.

Send one synthetic delivery through a board watch's configured channel immediately. This external side effect is limited to one test per watch every 30 seconds, is not saved in delivery history, and does not change the watch's real last-notified state.

Partially update a Vaquill board watch without changing its delivery channel. Omitted fields remain unchanged. Pause/resume and email updates are available on all plans; webhook destination, signing, and outbound-auth updates require Vaquill Business. This endpoint is free.
