Search arXiv preprints by keywords, author, or category. Returns metadata: arXiv ID, title, authors, abstract, categories, PDF/HTML links. Use arxiv_get with the arXiv ID to retrieve full text.

Retrieve an arXiv paper by ID (e.g., "2501.02725"). Default: metadata + abstract. With section or save_path: fetches HTML full text (available for papers from ~2024+). Older papers without HTML return metadata + abstract + PDF link.

Search Bundestagsdrucksachen (parliamentary documents) via DIP API. Matches title as a literal substring — NOT a keyword AND/OR search. An extra word breaks the match unless it appears verbatim, in that exact order, in the title. For example "Tiergesundheitsgesetz" alone finds dozens of documents, but "Tiergesundheitsgesetz Änderung" finds none, because real titles read "...Änderung des Tiergesundheitsgesetzes..." — reversed order and a different word ending. Prefer a single distinctive word (e.g. a law's short title) over a natural-language phrase. Returns metadata: Dokumentnummer, title, type, date, PDF URL. Use dip_get to retrieve full text (e.g., Gesetzesbegründung) of a specific Drucksache.

Retrieve full text of a Bundestagsdrucksache by Dokumentnummer (e.g., "19/27426" for BT-Drs. 19/27426). Returns the extracted text including Gesetzesbegründung. Use section for partial content. save_path is for export only — when the user wants the document as a file to keep or process elsewhere.

Search legislative processes (Vorgänge) in DIP. Returns Gesetzgebungsvorgänge with status and linked Drucksachen-Nummern. Useful for tracking a law through the legislative process or finding all related documents. Matches title as a literal substring — NOT a keyword AND/OR search (see dip_search); prefer a single distinctive word over a natural-language phrase.

Search Plenarprotokolle (parliamentary debate transcripts) with full text search. Returns protocols where the search term appears in the debate text.

Search EU legislation (directives, regulations, treaties) via EUR-Lex SPARQL endpoint. Returns CELEX numbers, titles, and dates.

Retrieve EU legislation from EUR-Lex by CELEX number (e.g., "32016R0679" for GDPR, "32001L0029" for InfoSoc). Returns full text in Markdown. Use section for partial content: "Art. 5", "Artikel 5", or "lines:100-200". save_path is for export only — when the user wants the document as a file to keep or process elsewhere.

Search for decisions and opinions of the Court of Justice of the European Union (CJEU) via InfoCuria. Returns list with case numbers, ECLI, dates, and document IDs for retrieval.

Retrieve a CJEU decision or opinion from InfoCuria by published case number, CELEX number or Logic Doc ID. Returns full text in Markdown with Randnummern as [Rn. 5]{.rn}. A published case number (e.g., "C-476/17", "T-108/25") is converted to its CELEX form internally, so all three forms work. A CELEX number (e.g., "62017CJ0476") or the "Logic Doc ID" from an icu_search result (e.g., "id_320668") resolve with one request fewer. Use section for partial content: "Rn 5-12", heading text, or "lines:100-200". Use save_path when you want the document written to a file for later use outside this conversation.

Search German state legislation (Landesrecht) by keyword. Returns results with IDs for retrieval via legis_get. Official abbreviations such as "HKG" or "PolG" are often more reliable than descriptive phrases. Covers all 16 Bundesländer. BUND does not support search — use legis_get directly.

Retrieve a specific law/norm from German federal or state legislation. BUND: id is "law/section" — law is the lowercase abbreviation (e.g. "bgb", "gg", "stgb"), section is just the number. An optional "§", "Art.", "Paragraph", or "Para." prefix on the section is stripped automatically, so "bgb/823", "bgb/§ 823", and "bgb/§823" are equivalent; use whichever prefix matches the document type (§ for codes, Art. for the Grundgesetz). Not every law is hosted under its plain abbreviation on gesetze-im-internet.de — some reissued laws use a different URL slug. If this returns "not found", a subscription provider that resolves abbreviations through its own index may still find it. Länder: id from legis_search results (format varies by state).

Get table of contents for a law — compact list of section numbers and headings. Much lighter than legis_get for navigating large laws. BUND: id is just the law abbreviation (e.g., "bgb", "stgb"). Länder: id from legis_search results.

List all 17 available German jurisdictions (BUND + 16 Bundesländer) with their backends.

Search for court decisions. Default source "bund": federal courts (BVerfG, BGH, BVerwG, BFH, BAG, BSG, BPatG). Source "BY": Bavarian state courts. Sources "NW", "NI" and "BB" use the official NRW, NI-VORIS and Brandenburg decision databases. Sources BW, BE, HH, MV, RP, SL, ST, SH, TH, HE use the official jPortal state decision portals. Returns list of decisions with metadata and doc IDs for retrieval.

Retrieve full text of a court decision by doc ID. Returns decision in Markdown format with metadata (court, date, file number, ECLI). Use source "BY" for IDs from gesetze-bayern.de (format: Y-300-Z-...).

Search the Austrian Rechtsinformationssystem des Bundes (RIS, ris.bka.gv.at). application="bundesrecht"/"landesrecht" searches the broad federal/state collections; results may be consolidated law (BrKons/LrKons) or authentic publications, identified by their returned applikation. A bundesland filter restricts state law to consolidated LrKons results. application="judikatur" = case law — set court (Justiz = OGH/OLG/LG, Vwgh = VwGH, Vfgh = VfGH, Bvwg = BVwG). Use sort="date" for the LATEST decisions. Judikatur results are Rechtssätze (legal principles); each lists its full decision text (Entscheidungstext) — fetch that with ris_get. NOTE: this is AUSTRIAN law. For GERMAN case law use rii_*, for German legislation use legis_*.

Retrieve a RIS document as Markdown. Pass the content_url returned by ris_search (preferred), or an id (Dokumentnummer) together with its applikation. Use section to pull only part of a document (token-preserving), or save_path to write the full document to disk and return metadata only.

Retrieve a single paragraph (§) of an Austrian consolidated law as Markdown — e.g. law="ABGB" paragraph="1295". application="bundesrecht" (federal) or "landesrecht" (state law; set bundesland). The surgical, token-preserving way to read ONE § instead of a whole statute.

Get the table of contents (Inhaltsverzeichnis) of an Austrian consolidated law — its §§ with headings — so you can then read one with ris_get_norm. Use the full title if an abbreviation fails (e.g. "Urheberrechtsgesetz" rather than "UrhG"). application="bundesrecht" (federal) or "landesrecht" (+ bundesland).
