About API Grátis
API Grátis (operated by APIBrasil Processamento de Dados LTDA) is a Brazilian API platform offering more than 170 APIs across 20 categories, covering CPF and CNPJ lookups, credit data, antifraud checks, vehicle data (including FIPE valuations), WhatsApp messaging, SMS, CEP/address lookup, and document validation. Access is provided via REST, official SDKs, webhooks, and MCP for AI agents. Billing is per-query or via monthly subscription, with published pricing for each API in the catalog and no card required to create an account.
The antifraud offering spans four areas: identity, vehicle history, company standing, and document regularity, totaling 137 APIs. Queries are made by submitting a document type (such as CPF, CNPJ, plate, or chassis number) to a gateway endpoint, which returns data such as cadastral status, ownership records, or fraud flags; risk interpretation is left to the calling system's own rules rather than being determined by the platform.
Additional API families include WhatsApp (messaging, files, buttons, lists via webhooks), SMS (for verification codes and notifications), cadastral data lookups (CPF/CNPJ status and company details), vehicle and FIPE data, CEP/address completion, document/certificate validation, and validation of emails, phone numbers, and registration data. The platform is intended for developers building onboarding, checkout, compliance, fraud prevention, and communication features for the Brazilian market.
