  title: TXCloud FraudShield API
  version: 1.0.0
  description: |
    The TXCloud FraudShield API provides fraud detection signals that enhance 
    identity verification, plus tools to manage fraud rules, blocklists, and 
    investigate suspicious activity.

    ## How It Works
    FraudShield is called internally by the Identity API during verification.
    Clients receive fraud signals in the verification response. These endpoints
    are for configuration, investigation, and advanced use cases.
