# x402_payment_flow_analyzer

As a CTO, analyze USDC payment flows involving x402 addresses to assess counterparty risk, trace transaction paths, and evaluate regulatory exposure. Input a wallet address or transaction hash to receive risk scores, flow diagrams, and compliance flags from Chainalysis and TRM Labs public APIs. Ideal for due diligence, fraud detection, and compliance reporting. Pass async:true to avoid timeout.

## Why x402_payment_flow_analyzer is rated Low

The tool reads and analyzes blockchain transaction data from public APIs (Chainalysis, TRM Labs) to produce risk scores and compliance flags. It does not move money, execute transactions, or modify data — it is purely investigative/analytical.

From the tool's own definition: "analyze USDC payment flows...assess counterparty risk, trace transaction paths...receive risk scores, flow diagrams, and compliance flags from Chainalysis and TRM Labs public APIs"

## Use case

AI agents call x402_payment_flow_analyzer to retrieve information from Gapup Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
