Critical Global Context for Internally-Built Risk Models
The Sift Score API adds critical external context to internally-built risk models. Detect global & industry threats with real-time risk scores powered by 1T annual consortium events. Build the way you want, without sacrificing access to the powerful tools in the Sift Console.
The Sift Score API is the Missing Piece for In-House Fraud Models
Building custom fraud detection models tailored to your unique data and risk patterns has its advantages. But limitations in data diversity and scope create security blind spots affecting every digital interaction. Fraud tactics like card testing and credential stuffing stay hidden until they cause significant revenue loss—or break the hard-earned trust your customers have in your business.
The Sift Score API connects internally-built fraud systems to our Global Data Network, delivering the same level of risk insight and Console access available to full-platform Sift customers.
What is the Sift Score API?
The Sift Score API is a modular fraud intelligence solution that delivers real-time risk scores derived from over 1 trillion annual events and 16,000+ fraud signals accumulated over 13 years. It delivers:
- A fraud risk score (0-100) to assess transaction legitimacy
- The top 20 risk signals explaining why an action was flagged
- Seamless API integration into internal fraud models and decision engines
How Does it Work?
The Sift Score API integrates with in-house risk engines fluently and without friction. When your internal risk engine submits real-time data via API calls (e.g., IP address, email, device fingerprint, transaction details), Sift cross-references that input against our Global Data Network.
An identity match or link is then made, and anomalies and patterns linked to fraudulent behavior can then be accurately identified in real-time. Industry-specific risk factors are applied to ensure relevance for your market.
Build How You Want To
The Sift Score API is built for data science-focused digital businesses on a journey to build a bespoke world-class fraud intelligence system.
Whether your team is running multiple custom machine learning models or relying on a rules-based risk engine, our API delivers data-driven precision directly within your existing fraud stack.
