Everything you need to know about implementing SiftlyAPI in your application.
10-17ms for cached responses and 22-25ms for complex analysis—faster than a user can blink. Your signup flow stays lightning-fast while scoring every signup for quality. That's 6x faster than our 100ms target.
Our parallel pipeline analyzes 4 key fraud signals: Email patterns (catches disposable/fake domains), IP intelligence (detects VPNs, bots, and suspicious locations), velocity tracking (stops signup farms), and user agent analysis (identifies automated browsers). Each factor is weighted by fraud risk.
Our system blocks 95% of fraudulent signups while maintaining near-zero false positives. We achieve 87.5% accuracy on IP detection alone, then layer in email, velocity, and behavioral signals for comprehensive fraud scoring.
Not at all. With 95% cache hit rates and 10-40ms response times, signup scoring happens invisibly. Your users get instant signups while you get quality insights. We're 50% faster with caching enabled.
Absolutely. 100% uptime with graceful fallbacks means your signup scoring never goes down. Built with Go for enterprise scale, we handle millions of requests with consistent 10-40ms performance. Beta launches in 30 days.
Dead simple. One POST request with email and IP gets you a trust score (0-100) and risk level in 10-40ms. Add it to your signup flow in 5 minutes. We provide detailed analysis, SDKs, and Zapier integrations for seamless implementation.
