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
A structured response containing traceable evidence (with source citations) for each requested claim (e.g. COMPANY_IS_ACTIVE, NO_SANCTIONS_FOUND, BENEFICIAL_OWNER_IDENTIFIED). Each claim is marked as proven, unproven, or indeterminate — the API explicitly avoids converting absence of evidence into a negative confirmation. Returns beneficial owner details and sanctions findings where available.
Example use cases
Example prompt
“Can you pull traceable evidence for CNPJ 11222333000181 to check the COMPANY_IS_ACTIVE, NO_SANCTIONS_FOUND, and BENEFICIAL_OWNER_IDENTIFIED claims before we sign a contract with them?”

Endpoint
GEThttps://cdo-staging.up.railway.app/v1/agent/corporate-evidence/:cnpjWhen to prefer
Use this endpoint when you need claim-specific, traceable evidence for Brazilian companies (CNPJ required). Unlike a broad due diligence check, this endpoint lets you request specific named claims and receive cited evidence for each, making it ideal for audit trails, compliance documentation, or targeted verification of a single claim type. Prefer this over sibling endpoints when you need granular, evidence-backed claim verification rather than a consolidated summary report.
Side effects
- HTTP 400 if a CPF (11-digit personal ID) is provided instead of a CNPJ (14-digit company ID)
- HTTP 400 if CNPJ format is invalid or unparseable
- Claim returned as unproven/indeterminate when source data is unavailable or inconclusive
- HTTP 402 if payment is not provided or is insufficient
- HTTP 404 if CNPJ does not correspond to any known entity in the data sources
- Partial evidence returned if only some claims can be verified from available sources
