# Index of core Spanish mercantile-law norms

`GET /api/v1/legal/norms`

Return the catalog of core Spanish mercantile-law norms (codes, laws, royal-decree-legislatives, regulations) structured by OpenMercantil. Each item links to its HTML page (`/ley/{slug}`) and its norm-detail API (`/api/v1/legal/norm/{slug}`). LICENSE: consolidated text from the BOE, re-used under Ley 37/2007; the official, authentic version is always boe.es. Informational only — NOT legal advice. Cached 24h. Returns 503 if the legal catalog is not deployed yet.
