Brazilian Company Registry Lookup by CNPJ (BrasilAPI)

brasilapi/cnpj-lookup

Returns the Brazilian company registry record for one CNPJ (the 14-digit company tax number): legal name and trade name, registration status and date, address, main and secondary activity codes (CNAE), legal nature, size class, capital, tax-regime history, and the list of partners with their roles. Personal data: partner records (the `qsa` list) hold natural persons' names, partially masked CPF, age band and role, and for a sole proprietor (MEI or individual entrepreneur) the legal name, address, phone and email are the person's own. Lookup by CNPJ only, one per call; no search by name. Data from BrasilAPI, passed through unmodified and served by Eden Engine; not an official BrasilAPI product.
