Search Dutch case law (jurisprudentie/uitspraken) via the official Open Data API and get back ECLIs with links to the ruling and a PrudAI viewer. This is a faceted search: filter by rechtsgebied, instantie, date range and document type. It does not do free-text keyword matching. If you already have an ECLI, pass it as query and the tool returns that single decision's summary. Use list_waardelijsten to discover valid rechtsgebied/instantie identifiers.

Run several Open Data lookups at once (3–10 entries). Pass ECLIs to resolve a batch of decisions' summaries in one call. Note: Open Data has no free-text matching, so non-ECLI terms fall back to facet-only results — prefer get_uitspraken_bulk when you already have the ECLIs. Use to cast a broad net before narrowing down via get_uitspraak.

Fetch the full text and metadata of a single Dutch court decision by ECLI, from the official Open Data API (data.rechtspraak.nl). Returns metadata (court, date, rechtsgebied, zaaknummer), the plain-text body, formal relations (conclusie/cassatie/etc.), and links to the ruling on rechtspraak.nl plus a PrudAI viewer. If the ECLI is not published or has no body text, the tool says so — do not invent or cite it in that case.

Fetch multiple Dutch court decisions by ECLI in one call (1–10 ECLIs) from the official Open Data API. Returns a per-ECLI result with the body text, metadata, relations, and links — or an error for any ECLI that is unpublished or not found.

List the Rechtspraak value lists (waardelijsten) used to build valid search filters: instanties, instanties_buitenlands, rechtsgebieden, proceduresoorten, niet_nederlandse_uitspraken. 'rechtsgebieden' and 'instanties' return the identifiers/URIs you pass to search_uitspraken (rechtsgebied / instanties). Call without a name to see the available lists.

Get the LiDO citation graph around a Dutch ECLI: rulings that cite it or are cited by it, referenced statute articles, and official publications, with typed Dutch link labels (e.g. 'Verwijst naar', 'Conclusie', 'Vernietigt'). Data comes from KOOP's live LiDO service (linkeddata.overheid.nl). Use it to position a ruling (is it a landmark? what does it cite?). Read-only and bounded (per-direction limit default 100, max 250). This returns structure, not full text — use get_uitspraak for the text of any neighbour.
