Sift
Sift (formerly Sift Science) is the San Francisco-based Digital Trust and Safety platform that protects more than 700 global brands from payment fraud, account takeover, content abuse, promotion abuse, and money movement risk. Sift's APIs ingest user, device, payment, content, and verification events, return real-time risk scores per abuse type, automate decisions through Workflows, ship a Verification API for step-up challenges, and operate a Console for analyst case management. Sift was founded in 2011, processes more than one trillion events per year, and reports a median annual loss prevented of about $4.2M per customer.
Sift publishes 6 APIs on the APIs.io network, including Decisions API, Events API, Labels API, and 3 more. Tagged areas include Fraud Prevention, Trust and Safety, Risk Scoring, Identity Verification, and Chargebacks.
The Sift catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Sift’s developer surface includes authentication, developer portal, documentation, API reference, getting-started guide, changelog, support, and 38 more developer resources.
