How this service works
One company from Brazil's CNPJ register (Receita Federal open data, via the community service BrasilAPI) by CNPJ: registered name, trade name, status, legal form, registered address and a link to the official register search. Company-level facts only; no partners or sole traders. Uncached: 404, not charged.
Output
A JSON object containing: the CNPJ used (id), the official registered name, trade name, company status, legal form, registered address, country code (br), the data source attribution (BrasilAPI / Receita Federal), and a link to the official register search. Returns HTTP 404 (not charged) if the CNPJ is not found.
Example use cases
Vendor due diligence for procurement
“I need to onboard a Brazilian supplier — their CNPJ is 60.746.948/0001-12. Can you pull their official registered name, trade name, current status, and legal form from the Receita Federal so I can check they're legitimate before we sign a contract?”
KYC enrichment for a Brazilian counterparty
“We're doing KYC on a Brazilian entity with CNPJ 00.000.000/0001-91. Fetch their company registration details — registered name, status, legal form, and address — from the official government data.”
Automated invoice validation
“An invoice just came in from a Brazilian company claiming CNPJ 07.526.557/0001-00. Can you verify that CNPJ against the Receita Federal register and tell me the official registered name and whether the company is active?”
Technical details
Endpoint
GEThttps://api.maxwellinternational.ai/v1/gov/br/companies?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, government-sourced company-level facts for a Brazilian entity identified by its CNPJ. It is ideal for KYC enrichment, vendor validation, invoice verification, or any workflow needing official Receita Federal data without standing up your own integration. Prefer it over generic web search when you need structured, machine-readable fields (name, status, legal form, address) rather than unstructured text. Note it covers company-level records only — not individual sole traders or partner details.
Side effects
- 404 Not Found – CNPJ does not exist in the Receita Federal register (no charge applied)
- Invalid CNPJ format – malformed or non-numeric CNPJ string may be rejected
- BrasilAPI upstream outage – community service may be temporarily unavailable
- Rate limiting or payment failure – x402 payment not processed, request blocked
- Partner/sole-trader CNPJs (CPF-based) are explicitly out of scope and will not return data
