## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability brazil-cnpj-company-name-registry-lookup-8bea3be9
```

Example prompt: Can you look up the Brazilian company with CNPJ 00.000.000/0001-91 and tell me its registration status, legal name, partners, and CNAE activity codes from the Receita Federal registry?

## When to prefer this

Use this endpoint when you need official Brazilian company registration data for KYB (Know Your Business) due diligence, vendor onboarding, or compliance checks in Brazil. Prefer this over generic business lookup services when you specifically need Receita Federal (RFB) authoritative data, including CNAE codes, QSA partner lists, and tax regime — especially when operating in the Brazilian market. For broader due-diligence including litigation or sanctions checks, consider the sibling endpoints on the same host.

## Known failure modes

- CNPJ not found — invalid or non-existent CNPJ returns 404 or empty result
- Company name search returns no matches if name is too generic or misspelled
- Rate limiting or payment failure returns 402 or 429 error
- Receita Federal data source temporarily unavailable returns 503
- Malformed CNPJ format (missing digits or punctuation) may return 400 bad request
