How this service works
Returns Brazilian company data from BrasilAPI (CNPJ lookup, MIT licence): legal name, trade name, status, opening date, legal nature, CNAE activities, address, share capital, and partners (QSA). CNPJ check digits are validated before any network call. Rate limit: BrasilAPI allows ~3 req/s.
Output
Returns a JSON object with the company's CNPJ, legal name, trade name, registration status and status date, opening date, address (street, city, state, postal code, country), phone, email, main and secondary CNAE activity codes with descriptions, list of partners with roles and countries, legal nature code and description, share capital, and a source attribution to BrasilAPI.
Example use cases
Supplier due diligence check
“I need to verify a Brazilian supplier before onboarding them — their CNPJ is 33.000.167/0001-01. Can you pull their legal name, registration status, address, and list of partners from the federal registry?”
KYC enrichment for Brazilian entity
“As part of our KYC process, please fetch the full company profile for CNPJ 60.701.190/0001-04, including legal nature, share capital, opening date, and main business activity code.”
Check if Brazilian company is still active
“Is the company with CNPJ 11.222.333/0001-81 still active in Brazil? I need their current status and status date from the official registry.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/company/br?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative Brazilian company registry data (Receita Federal / BrasilAPI) for a known CNPJ number. Prefer this over generic web scraping when you need structured fields like legal name, status, CNAE codes, partners, and share capital in a single call at a predictable low cost.
Side effects
- Invalid or malformed CNPJ (not 14 digits) returns a validation error
- CNPJ not found in Brazilian federal registry returns a not-found error
- BrasilAPI upstream unavailability may result in a 502 or timeout
- Recently registered or deregistered companies may return stale or missing data
