  title: SEON REST AML Email API
  description: SEON's fraud prevention and anti-money-laundering REST API. Combines digital-footprint analysis, device fingerprinting, and machine-learning risk scoring to return real-time fraud scores and enriched intelligence from an email address, phone number, IP address, or full transaction payload, plus AML screening and transaction labeling. All requests authenticate with an X-API-KEY header and are case-sensitive.
