What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

• 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 text does not mean the law is absent. Use child apiHref links or lookup_provision w

• 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  Authoritative text of one provision, with in-force window, repealed/prospective status, concept tags, transposition edges and full provenance.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 (`consolidated` with a date, `as-adopted`, or `unknown`) and carries the one-line `se

• 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 prove when it applied. Pass a returned expression ID to lookup_provision to read th

• 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 activity, product, Spain or France, and date. Country links carry their relation

• 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's own HTTP account access.

• 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; inspect the cited current result before relying on a connection. Read-only.

• 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 silent about what that information now includes, and about which amending act p

• 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 provisions that USE a phrase, this returns the law that DEFINES it, verbatim. A t

• 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 what a term means IN THIS ACT rather than in the corpus at large — several instrum

• 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 each wording is the law in that language. Use it to answer 'what do the German and

• 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, which takes it from the AVMSD, counts for the AVMSD's definition) or CITE a def

• 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 through), the instruments that cite a defining provision, and the term's labels in t

• 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 language-neutral way to line up EU and national law on the same subject.

• 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_national_implementations.

• 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`, null where the citation is act-level — which is most of them, and is not a defect

• 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 monthly Nexus allowance; the legislative text itself is always free.

• 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 so when citing. Check evidenceStatus: a current national consolidated reading ai

• 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 the UCPD Guidance' and be checked. EVERY ROW IS NON-BINDING (`binding: false`). 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 UNREVIEWED model drafts — say so if you quote one. Feed a result's conceptId to get

• 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 provisions with anchor provenance, article-level transposition links (method, confidence

• 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, draft topic descriptions and jurisdiction notes, and recorded findings (gaps and d

• 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. (The one tool in this catalogue that writes anything is request_ingestion, whi

• 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 appearing, a provision now repealed), 'minor' (wording changed, or the stored text mov

• 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 instrument. The answer then says which kind of absence it is: `metadata-only` (the in

• 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 one or two sentences; state any testable expectations. Lexiara validates the ta

• 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 never returned. This is read-only and does not start, repeat or alter acquisiti

• 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, failed, confirmed_unavailable. A fetch that timed out is `failed` and will be

• 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 expectation results. Repeat your original lookup with the handles. Pass `expres
