CPF/CNPJ FAQ

How do I test in sandbox?
Use an API key prefixed sk_test_ and the test documents listed above. No charges are made in the sandbox environment. You can create a sandbox API key directly in the portal, no need to contact us.
Does the integration work on mobile?
Yes. CPF/CNPJ lookups are done exclusively on the backend — never directly from the mobile app. There is no widget or SDK. Just an HTTP call from your server.
Is there a rate limit?
Yes. The default limit is 100 req/s per API key. If your demand requires more, contact us to adjust the limit at no extra cost.
Is the returned data LGPD-compliant?
Yes. Campeão Sec acts as a data controller in compliance with LGPD. The queried data comes from public registries, every access is logged and auditable, and the data is never resold or shared with third parties.
