# Get Banco de España sector ratios for a company CNAE

`GET /api/v1/company/{slug}/bde`

## Request

- Base URL: `https://openmercantil.es`
- URL: `https://openmercantil.es/api/v1/company/{slug}/bde`
- 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/company/:slug/bde/get.ts> (a function with typed inputs; its response is checked against the schema)

Join the already admitted company_public_v2 identity to the immutable Central de Balances sector projection using the company's two-digit CNAE. The response binds both immutable generations. This is sector benchmarking, not a supervised-entity record, company-specific financial statement or score. coverage_status distinguishes a missing CNAE, an unprojected sector and a match; empty coverage never proves that no Banco de España data exists.

## Path parameters

- `slug` string, required

## Response `200`

CNAE sector-ratio projection or its documented empty shape

- CompanyBdeResponse: Banco de Espana Central de Balances ratios for the company's two-digit CNAE sector. These are sector metrics, not a supervised-entity record or company score.
