Frequently Asked Questions about the CPF API
Everything you need to know about our CPF lookup and validation API
Data and Quality
All data comes directly from the Brazilian Receita Federal. Our base holds 233+ million official records, refreshed regularly. No scraped or unofficial data.
Yes. Our base is synchronised with official Receita Federal records and we deliver 99.8% accuracy. Very different from amateur APIs running on stale data.
Our API responds in under 100ms on average. We use dedicated servers and a CDN to keep performance high even under heavy request volume.
Plans and Payment
Simple and professional: 1) create your account in the Dashboard, 2) choose your plan inside the platform, 3) pay by PIX straight from the dashboard (QR code + exact amount), 4) receive your token and start using it right away.
PIX fully organised through the dashboard. You get the charge inside the platform with a QR code, the exact amount and a clear due date. No chasing by message, no guessing the amount, no confusion. Once paid, access is released automatically along with the tax invoice.
Of course. Cancel automatically from the dashboard whenever you want. No red tape, no retention calls. Your company, your rules.
Yes, automatically. An electronic invoice is issued on the payment date and sent by email — ready for your finance team, not a bare PIX transfer receipt.
Technical / Integration
Very simple. We provide ready-made examples in PHP, JavaScript, Python and cURL, plus complete documentation with real use cases. Integration takes under 10 minutes.
Transparent, fair limits: the free plan includes 10 lookups/month for testing. Paid plans include 10,000 lookups/month and overage costs R$ 0.01 per lookup via PIX. Everything stated clearly — no surprises.
Yes. An interactive playground right here on the site, plus the official test CPF (000.000.001-91) for your development environments.
We run at high availability (around 99.9%), with 24/7 monitoring and redundant infrastructure. Very different from homemade APIs that keep going offline.
Support
Professional email support with a reply within 4 business hours, handled by a specialised technical team — not one developer answering from a phone at midnight.
Complete, up-to-date documentation. Endpoints, parameters, error codes and practical examples. Everything you need, without having to ask over chat.
Our team helps you. Integration support is included on every plan. We review your code, suggest improvements and make sure it works properly.
