Call before publishing a claim that cites EU law. Checks that the cited instrument exists in our pinned corpus, that the cited article exists within it, and whether your quoted text actually appears in that article. Covers the AI Act, GDPR, NIS2, DORA and the Cyber Resilience Act. Returns the official article text with a EUR-Lex link. Citation verification only: it never gives legal advice or classifies systems.
