# BORME act type → governing norm bridge (full or single)

`GET /api/v1/legal/act-map`

## Request

- Base URL: `https://openmercantil.es`
- URL: `https://openmercantil.es/api/v1/legal/act-map`
- Auth: one of:
  - none
  - API key in header `X-API-Key`
  - HTTP bearer
- TypeScript: <https://skmtc.dev/openmercantil/apis/openmercantil-public-api/docs/api/v1/legal/act-map/get.ts> (a function with typed inputs; its response is checked against the schema)

Return the bridge mapping each BORME act type (constitución, nombramiento, ampliación de capital, disolución, concurso, …) to the norm and articles that govern it — the law↔data connection that lets an LLM answer 'which law governs this registry act'. Without `{acto}` returns the full map; with `/act-map/{acto}` returns a single mapping. License: BOE / Ley 37/2007. Informational only — NOT legal advice. Cached 24h.
