- User Screening: Analyze account-level events (registrations/logins) for suspicious patterns.
- Transaction Management: Retrieve historical results for orders or user screenings.
- Feedback Loop: Approve, Reject, or Blacklist transactions directly through the AI interface to improve the detection engine.
