- `eurlex\_lookup\_celex`: Resolve an EU legal citation — a CELEX number, ELI URI, ECLI, or an OJ citation naming its act type and year \(e.g. "Regulation \(EU\) 2016/679", "Directive 95/46/EC"\) — to its canonical CELLAR work, confirming it exists before you fetch or traverse it. Returns the work URI, confirmed CELEX number, doc

Matches both preferred and alternative \(non-preferred\) labels, so a common synonym reaches the concept it stands for. Returns each concept URI, its preferred l

- `eurlex\_query\_sparql`: Run a raw, read-only SPARQL SELECT against the CELLAR Virtuoso endpoint — an escape hatch for CDM ontology traversals the curated tools do not cover.
