Verify x402 endpoint payment integrity
The agent receives a detailed report on the endpoint's payment challenge, including any critical drift in receiving addresses, networks, or assets, ensuring safe interaction with third-party services.
How it works
The agent calls the /x402/verify endpoint to inspect a stranger's x402 endpoint before making a payment. It analyzes the live payment challenge and compares it against previous observations. The agent checks for critical drifts such as changed receiving addresses, networks, or assets. It reports what the endpoint declares but notes that it does not certify the operator, allowing the user to make an informed decision about trust.
