How this service works
Pay-per-call Brazilian business intelligence for AI agents, paid via x402 in USDC on Base.
Output
Returns a JSON object containing the CNPJ, the company's official razão social (corporate name), their situação cadastral (e.g. ATIVA), and business intelligence signals including whether the company is active, whether it has a QSA (ownership/management structure), and the count of secondary CNAE activity codes registered.
Example use cases
Supplier due diligence before onboarding
“Before we onboard this Brazilian vendor, can you check CNPJ 12.345.678/0001-99 to confirm their company name, that they're in active registration, and whether they have a formal ownership structure (QSA)?”
Automated KYB check for Brazilian customer
“We have a new Brazilian business customer who gave us CNPJ 19.131.243/0001-97 — can you verify their company name and confirm their cadastral status is active before we approve their account?”
Market research on Brazilian competitor
“I'm researching a Brazilian competitor — their CNPJ is 07.526.557/0001-00. Can you get me their official corporate name, registration status, and how many secondary business activities they're registered for?”
Technical details
Endpoint
GEThttps://br-intelligence.brverify-api.workers.dev/v1/dossier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured Brazilian company intelligence — corporate name, active status, ownership signals — from a CNPJ number in a pay-per-call model without a subscription. Ideal for AI agents performing KYB checks, supplier due diligence, or market research on Brazilian entities. Prefer this over manual Receita Federal lookups when you need programmatic, agent-accessible access paid in USDC via x402.
Side effects
- Invalid or malformed CNPJ returns an error — the API accepts formatted or unformatted CNPJs but invalid check digits will fail
- Company not found in the registry returns a not-found error
- Payment failure via x402/USDC on Base blocks the request before processing
- Rate limiting or upstream registry unavailability may cause timeouts
