Test your x402 client for a tenth of a cent: a real, non-refundable USDC payment on Base mainnet that returns the details of the payment you just made — x402 version, header, scheme, network, payer, amount, validity window and nonce — with the settlement receipt in the response headers. Built for debugging agents, wallets and x402 integrations.
