Before you pick one

CNPJ endpoints are limited to a few requests per minute, and government hosts can be slow outside Brazilian business hours. Set a timeout and keep a fallback provider for CEP.

Open an API’s page to see the exact request we send, the answer it gave, and how many of the last 30 days it was up. If it is marked CORS you can run the request from the page itself.
