API Grátis API
Overview
API Grátis is a Brazilian API aggregator that bundles multiple free utility services including CEP (postal code) lookup, CNPJ (company registry) data, vehicle plate information, and more — all under a single authentication token. Most endpoints target Brazilian government data that would otherwise require scraping official sites. The platform is designed for Portuguese-speaking developers building apps that integrate with Brazilian public data.
Beginner Tip
Create a free account at apigratis.com.br to receive a Bearer token for authenticated endpoints; some simpler utilities like CEP lookup may work without authentication. All documentation is in Portuguese, so use a translation tool if needed.
