# Full KYB profile in one call, with registration + partners + branches + sanctions + Central Bank + public contracts ($0.05 via x402)

`GET /v1/empresa/enriquecer/{cnpj}`

## Request

- Base URL: `https://api.brazilayer.com`
- URL: `https://api.brazilayer.com/v1/empresa/enriquecer/{cnpj}`
- Auth: none declared

## Path parameters

- `cnpj` string, required

## Response `200`

Enriched company profile aggregating all four datasets

- object
  - `cnpj` string
  - `cadastro` object
  - `integridade` object
  - `banco_central` object
  - `contratos_publicos` object
  - `fontes` object

## Other responses

- `402`: x402 payment required. The `payment-required` response header carries base64 JSON with accepted payment options (scheme "exact", USDC on Base, amount in 6-decimal units, payTo address). Sign an EIP-3009 authorization and retry with the `payment-signature` header. x402 client libraries automate this. If you are not using an x402 client, read the JSON body instead: it states the price and links the free sample of this dataset plus the free tools.
- `404`: Error envelope: { erro: { codigo, mensagem } }
