Fraudulent Transaction Detection

This agentic AI task detects fraudulent e-commerce activities - crucial for compliance monitoring and fraud detection agents. The task configuration outlines how to:

  • Monitor transaction patterns and behavioural anomalies

  • Evaluate authentication and identity risk factors

  • Score suspicious activities and risk levels

  • Generate fraud detection alerts with evidence

  • Recommend appropriate compliance responses


As a modular task, it integrates with payment and authentication systems, enabling AI agents to execute systematic fraud detection within existing e-commerce workflows. The task specification includes outputs for pattern analysis, risk assessment, and alert generation, adaptable across various marketplace contexts and security requirements.
