Before your agent updates a contract clause or a compliance rule that depends on a law: see exactly what changed in a French or EU article between two dates — resolves the version in force at each date, from the official LEGI and EUR-Lex datasets, and returns a word-level diff plus a git-style unified patch with both versions' metadata. Covers 12 major French codes and statutes and key EU acts (GDPR, DSA, AI Act, MiCA and more).
