About us

The CNPJAPI is the CNPJ lookup and data integration platform operated by GUIDI SISTEMAS E SERVICOS EM TECNOLOGIA DA INFORMACAO LTDA, a Brazilian information technology company active since 2010. We deliver the online CNPJ lookup and the REST API used to integrate public data from Brazil's Federal Revenue Service into systems, ERPs, CRMs and onboarding flows.

We are not a newly created project: behind CNPJAPI there is an established company, with its own CNPJ and more than a decade of experience in software development.

Why this matters

When you integrate a registry-data API, you are trusting whoever is behind it. CNPJAPI is maintained by a real, active and identifiable company - with an address, a CNPJ and a track record verifiable in the Federal Revenue Service's own public database.

In fact, the data on this page (legal name, registration status and founding date) comes from the exact same source our API serves: Brazil's Federal Revenue Service. You can look up our own CNPJ through the lookup API.
