Card networks were forced to keep these layers separate for decades. Authorization is just an issuer saying 'this account can spend up to X here right now.' It doesn't promise capture, doesn't validate that the merchant delivered, doesn't predict chargeback risk. Settlement comes hours or days later, and disputes run on a different timeline. Bundling these in agent stacks tends to break in the same places card networks already worked through. Curious whether x402 ends up with something like a reason-coded dispute layer, or whether escrow contracts absorb that role.
The separation between payment approval and task escrow points to a useful product rule: sell a bounded job before building the full agent stack. Define the input, output, price, evidence, and refund condition for one request. Charge before runtime. A paid request gives you a real signal about which outcome matters and where the buyer needs proof. After a few deliveries, compare the requests and keep the steps that repeat. Those steps are the right candidates for automation; the exceptions should stay visible. This keeps payment, work evidence, and automation from being confused, while turning an agent idea into a service you can improve from actual demand.
