search

Search Lexiara's bounded EU and UK legislation corpus. Returns compact, citable results with opaque ids; pass an id unchanged to fetch for the provision text and provenance.

fetch

Retrieve one search result by its opaque id, including provision text, canonical URL, authority status and source provenance. metadata.structure provides parent/child addresses; an empty container tex…

lookup_provision

Authoritative text of one provision, with in-force window, repealed/prospective status, concept tags, transposition edges and full provenance. `stand` says what date the served text speaks as of (`con…

list_work_versions

Find same-language publisher expressions for one EU act. Each entry has an exact expression ID, source hash and a consolidation marker or as-adopted label. These markers identify text; they do not pro…

search_legislation

Ranked full-text search over provision text. Results carry work, eId, status and provenance — feed a hit's work+eId to lookup_provision for the complete payload.

explore_role_requirements

Research source-bound EU role requirements with exact passages, act-specific definitions, conditions, unknown facts and EN/FR/DE/IT official source availability. Select multiple roles and an optional …

list_saved_role_views

List private role and country research views belonging to the connected account. Each view is a snapshot for comparison, not a compliance verdict. Read-only; saving and deleting views require a person…

get_saved_role_view

Recheck current official passages and connections against a private saved view. The change list separates later publisher versions, parser corrections, newly acquired material and review status; inspe…

provision_context

The cross-reference neighbourhood of a provision plus its amendment history. Use this when a provision's relevance is not on its face: a duty that says 'the information referred to in Article 6(1)' is…

define_term

The definition of a term of art, and the provision that gives it. Ask this BEFORE search_legislation whenever the question is what a phrase means ('durable medium', 'taxable person'): search returns p…

work_glossary

The act's glossary: every term it defines, alphabetical, with the publisher's own wording verbatim and the provision that defines each one. Use it to orient in an unfamiliar instrument, or to check wh…

term_languages

How an act words one of its defined terms in each language version held. NOT a translation: an EU instrument is equally authentic in all 24 official languages (Regulation No 1/1958, article 4), so eac…

list_concepts

Terms of art ranked by how many instruments in this corpus DEFINE them, BORROW them from another act (followed through every intermediate act — an act that takes 'video-sharing platform' from the DSA,…

concept_family

One defined term across the whole corpus: each distinct WORDING with the publisher's own text and the instruments that write it, every instrument that borrows it (with the chain of acts it passes thro…

provisions_by_concept

Cross-jurisdiction view of one legal concept: every provision tagged with the given EuroVoc concept, with tagging method and confidence. E.g. 'eurovoc:4585' (VAT), 'eurovoc:4392' (VAT rate). The langu…

related_works

Edges between instruments: which national laws transpose a directive (direction 'in'), or what an instrument implements/amends (direction 'out'). Instrument-level; for article-level links use find_nat…

work_mentions

The act-level overview: every provision of every instrument in this corpus that names the given act, grouped by citing instrument, with the article of the act each citation resolved to (`targetEId`, n…

provision_history

Prior and successor versions of one provision across consolidations — how the text got to its current form. Lexiara Nexus data requires an API key on a signed-in account. The free plan carries a mont…

find_national_implementations

National provisions implementing one EU provision, with method and confidence per link. DERIVED data, not published by any authority: treat links not marked method='human' as leads to verify, and say …

guidance_for_provision

Sections of official GUIDANCE that discuss one provision — Commission notices and guidelines on the act, quoted verbatim with the section number the publisher prints, so an answer can cite '§2.8 of th…

list_topics

Curated obligation topics ('Pre-contract information') under a subject head, each with a one-paragraph orientation and per-jurisdiction anchor counts. Descriptions with editorialStatus='draft' are UNR…

get_topic

Everything a topic page shows: the orientation paragraph (with its draft/published editorial status), per-jurisdiction legal-status notes (GB notes carry the assimilated-law caveat), anchored provisio…

recent_changes

Change feed: provisions added or modified, filterable by jurisdiction, concept and date. `detectedAt` is when Lexiara observed the change — legal in-force dates come only from the provision itself.

list_review_queue

The AUTO-GATED backlog from one place, newest first: unreviewed article-level transposition links with BOTH provision texts side by side and the stored reasoning, model/low-confidence concept tags, dr…

list_follows

The instruments, provisions, subjects, jurisdictions and verticals this API key follows. READ-ONLY: creating or removing a follow is an HTTP POST/DELETE to /v1/follows, and no tool here dispatches one…

follow_updates

The digest: every change the corpus observed on followed law, each with a SIGNIFICANCE grade and the reasoning behind it — 'major' (a new consolidation whose version point advanced, a provision appear…

get_coverage

Per-source coverage and freshness. Call this first when unsure whether Lexiara holds the law you need — absence of coverage means 'not here', never 'does not exist'. Pass `work` to ask about ONE inst…

request_ingestion

When a lookup returns `coverage` with `requestable: true`, ask for the missing instrument instead of stopping or guessing. Give the CELEX (or an EU ELI), the language and the version point; say WHY in…

list_ingestion_requests

List up to the latest 50 ingestion requests belonging to your account, newest first. Each row includes private status fields such as `intent`, `created_at` and `origin`; another account's requests are…

get_ingestion_request

State, stage, reason code and the time to wait before asking again, for one request you made. States: already_available, queued, running, available, partial, needs_clarification, needs_source_approval…

get_ingestion_result

The published handles — expression id, work ELI, the /v1/works/text and /v1/provisions addresses — plus the source manifest (publisher URL, content hash, bytes, retrieval time, parser version) and the…
