How this service works
Return traceable evidence for claims about a Brazilian company (e.g. COMPANY_IS_ACTIVE, NO_SANCTIONS_FOUND, BENEFICIAL_OWNER_IDENTIFIED). Clearly reports when a claim cannot be proven; never converts absence of evidence into a negative confirmation. CNPJ only.
Output
An evidence object containing traceable proof (or explicit acknowledgment of absence of proof) for each requested claim (e.g. COMPANY_IS_ACTIVE, NO_SANCTIONS_FOUND, BENEFICIAL_OWNER_IDENTIFIED), sourced per-claim with structured citations. Never falsely confirms a negative from missing data.
Example use cases
Example prompt
“Can you pull traceable evidence for CNPJ 11.222.333/0001-81 — specifically check whether the company is active, if there are any sanctions found, and whether a beneficial owner has been identified?”

Endpoint
GEThttps://cdo-production.up.railway.app/v1/agent/corporate-evidence/:cnpjWhen to prefer
Use this endpoint when you need verifiable, source-cited evidence for specific compliance claims about a Brazilian company — particularly for KYB (Know Your Business) workflows, sanctions screening, or beneficial ownership identification. Prefer this over generic company lookup APIs when auditability and explicit claim-based evidence are required, and when working exclusively with Brazilian CNPJ identifiers.
Side effects
- HTTP 400 if a CPF (11-digit personal ID) is submitted instead of a CNPJ
- HTTP 400 if CNPJ format is invalid or cannot be parsed
- HTTP 402 if payment is not provided (x402 payment required)
- HTTP 404 if the CNPJ is not found in any source
- HTTP 500 for upstream data source failures
- Claim returned as unverifiable if evidence is absent rather than confirmed negative
