Example prompt: Can you look up the Brazilian company with CNPJ 11222333000181 and tell me its registered name, trade name, current status, address, and who the partners are?

## When to prefer this

Use this endpoint when you need to verify or enrich data about a Brazilian legal entity using its CNPJ number. Ideal for KYC workflows, supplier onboarding, invoice validation, or any context requiring authoritative Brazilian company registry data. Prefer this over generic web scraping when you need structured, reliable data from the official ReceitaWS source.

## Known failure modes

- Invalid CNPJ format (not 14 digits) — returns validation error
- CNPJ not found in ReceitaWS — returns not found or empty result
- ReceitaWS upstream unavailable — returns 5xx or timeout
- Payment not included or invalid — returns 402 Payment Required
