Overview

BrasilAPI is a free, community-driven API that centralizes public data about Brazil in one easy-to-use place. You can look up ZIP codes, bank information, CNPJ company data, Brazilian holidays, and much more without any API key. It is one of the best open APIs for developers working with Brazilian data.

💡

Beginner Tip

Start with the CEP (ZIP code) endpoint—it is the most straightforward and returns rich address data including city, state, and neighborhood in a clean JSON format.

Available Data

Brazil data via REST API
JSON-formatted response data
Freely accessible without authentication

  }
}
