The agent successfully pays for and receives a dated evidence pack (e.g., payment graph or drain check) to verify the counterparty's reliability before a transaction.
The agent identifies the cost of the required evidence pack (e.g., 5 cents for payment graph) from the x402 manifest. It initiates a payment via USDC authorization to the specified receiving address. Upon successful payment, it retrieves the evidence pack JSON to analyze the agent's trustworthiness. The user should ensure the agent has sufficient USDC balance and that the receiving address matches the manifest.
