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 against document title — not full text. 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 or save_path to save to file.

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.

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". Use save_path to save to file instead of returning content.

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 case number or CELEX number. Returns full text in Markdown with Randnummern as [Rn. 5]{.rn}. Use section for partial content: "Rn 5-12", heading text, or "lines:100-200". Use save_path to save to file instead of returning content.

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" (e.g., "bgb/823", "gg/Art. 1", "stgb/§ 242"). 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 "bayern": Bavarian state courts (AG, LG, OLG, VG, VGH, FG, ArbG, LAG, BayVerfGH). 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" = consolidated federal/state law; 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).
