api.brazilayer.com/v1/cnpj/situacao/:cnpj
Does this CNPJ exist in the official Receita Federal registry, and is it active? Returns existence, registration status (situacao_cadastral: Ativa=active, Suspensa=suspended, Baixada=closed) with date, headquarters/branch flag and state. Cheapest paid check in the catalog: digit arithmetic alone cannot tell a well-formed number from a real, active company. Free sample, no payment: https://api.brazilayer.com/v1/cnpj/amostra

Verification
Checked 6 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.
