## Known failure modes

## How this service works

Brazilian company registry lookup by CNPJ (the 14-digit national company tax ID). Returns the legal name (razão social), trade name, registration status and reason, start date, legal nature, company size, share capital (BRL), primary economic activity (CNAE code + description), contact email/phone, full address, and the partners/officers (QSA — name + role). Free, open Brazilian government data (Receita Federal via BrasilAPI). The canonical "who is this Brazilian company" lookup for KYB, diligence, and cross-border onboarding — complements business.lei (GLEIF) and business.sos-search (US).

## Output

Returns a JSON object with ok:true and an items array containing one company record with fields: cnpj, legalName, tradeName, status, statusReason, startDate, legalNature, primaryActivity, primaryActivityCode, shareCapitalBRL, size, phone, email, address (street, number, district, city, state, zip), and partners (name, role). Also includes a source object with provider, URL, and license info.
