Questions

Does the ReceitaWS API need an API key?

No. The sample request on this page was answered without a key, token or account. Note: The free endpoint allows three requests per minute.

Can I call the ReceitaWS API from the browser?

Not directly. receitaws.com.br did not send an Access-Control-Allow-Origin header to our verifier on Oct 3, 2026, so browsers block the response. Call it from a server or a serverless function.

Is the ReceitaWS API working?

At the check on Oct 3, 2026 it returned HTTP 200 with the expected data in 301 ms. The status at the top of this page shows the most recent result we have.
