Search EUR-Lex with structured filters (free text, date range, document type, author, language). Returns a paginated list of matching documents with CELEX numbers, titles, and dates. Use this when the user wants to find documents matching a topic or filter; use lex_get_document afterwards to fetch full content of a specific result.

Fetch the full parsed content of a single EU document by CELEX number. Returns metadata (title, type, dates, author, ECLI/ELI, keywords) plus structured body (articles, sections, tables, annexes). Articles are individually addressable with id, number, title, and content. Use this when the user has a specific CELEX or wants the body of a known document.

Fetch metadata only for a CELEX (title, dates, type, author, ECLI/ELI, keywords, subjects) — significantly faster than lex_get_document because it skips body parsing. Use this for quick "what is this document" lookups or before deciding whether to fetch the body.

Fetch a parsed document from any EUR-Lex URL — useful when the user pastes a link from their browser. Extracts the CELEX from the URL and returns the same shape as lex_get_document plus sourceUrl and extractedCelex echoes.

List documents published to the Official Journal recently. Default window is 7 days. Filterable by document type, author, and language. Use this when the user asks "what was published this week" or wants a delta over a date window.

Find documents that cite this CELEX (inbound edges). Returns source documents grouped with their edge type (reference, amendment, repeal, implementation, legal-basis, proposal). Use to see who depends on or modifies a given act.

Find documents this CELEX cites (outbound edges). Returns target documents grouped with their edge type. Use to see what an act relies on, amends, or implements.

Fetch both inbound and outbound citations for a CELEX in one call, with per-edge-type counts. Use when the user wants a holistic view of how a document sits in the citation graph.
