Overview
Cep.la is a free Brazilian API that lets you look up address information using a Brazilian postal code (CEP). It returns details like street name, neighborhood, city, and state in a simple JSON format. No API key is needed, making it a great starting point for any app that handles Brazilian addresses.
Beginner Tip
Brazilian CEPs are 8-digit codes; you can pass them with or without a hyphen (e.g., 01310-100 or 01310100). The API returns null for invalid or unknown CEPs.
