# Detail of a single mercantile-law norm (with act↔norm bridge)

`GET /api/v1/legal/norm/{slug}`

Return one norm's BOE/ELI identification, its key articles (each with canonical URL + a flag for seeded consolidated text), the BORME act types it governs (the law→data bridge) and a single AI-citable atomic fact (`citable_fact`). LICENSE: consolidated text from the BOE, re-used under Ley 37/2007; the official version is boe.es. Informational only — NOT legal advice. Cached 24h.
