Will an agent's payment to your x402 endpoint go through? One unpaid call: checks the 402 and payment request (v1/v2), the token's EIP-712 domain against the contract on-chain (the usual cause of invalid-signature payments), network, amount, payTo, timeout, CORS for browser agents, resource URL and Bazaar discovery, with exact fixes. Never pays. $0.10 per call. Not charged for errors or "need more detail" answers.
