Verisoul

Verisoul is a fake-account and fraud detection platform that helps businesses stop bots, fake signups, and multi-accounting. It combines device fingerprinting, network and location signals, bot detection, email intelligence (risk, deliverability, breach, and identity signals), phone validation, and account linking with an automated rules engine and ML models. Verisoul also offers hosted identity verification products — Face Match (liveness/selfie dedup) and ID Check (government-ID document verification) — and manages biometric capture, consent, and retention on the customer's behalf. It exposes a REST API (Account, Session, Lists, Phone, Email Intelligence, Face Match, ID Check) authenticated with an x-api-key header, plus web and mobile SDKs and signed webhooks. Verisoul is backed by 500 Global.

Verisoul publishes 8 APIs on the APIs.io network, including Account API, Email API, Enrollment API, and 5 more. Tagged areas include Company, Fraud Detection, Identity Verification, Fake Account Detection, and Device Fingerprinting.
