# Checkup

> Checkup for x402 buyer clients. Pay once and get a field-by-field diagnosis of the payment your client signed (amount, recipient, validity window, clock offset, nonce, EIP-712 signature) and of the request that arrived, plus the facilitator's verify and settle results. Base mainnet payments get the full diagnosis; Base Sepolia payments get a preview with the status of each check only.
