Prepaid, no monthly fee, no contract. Credits never expire.
From customer onboarding to database enrichment
A single API key unlocks 100+ endpoints — from a R$ 0,16 basic registry lookup to a full credit report.
Fintechs, marketplaces, insurers and SaaS platforms
Check whether the CPF or CNPJ exists, is in good standing at the tax authority and matches the name given — before approving the account. One call, an answer in seconds, no manual review.
Marketing, growth and data teams
You have only the CPF or CNPJ — we return phone, email and address to complete the record. From R$ 0,29 per enriched row.
Collections, credit recovery and back office
Find people who went silent: every known phone (with WhatsApp flag), alternative addresses and emails — plus a death check, so you never chase someone who has passed away.
Procurement, tax and invoicing
Before invoicing or onboarding a supplier: status at the tax authority, Simples Nacional tax regime, state registration in Sintegra and the company's list of partners.
No contract, no monthly fee, no card to try it — prepaid: you only pay for what you query.
From registry data to credit in a single API
Start with the R$ 0,16 registry lookup and switch on premium endpoints when you need them — same GET, only the slug changes.
