In 3 years, the useful version is not just invisible payments. It is invisible until the receipt needs to be reviewed.
For an agent payment, I would want: payment_request_id, asset/amount, payee, mandate_scope, service_version, result_hash, failure/refund rule, and the field that would stop the next payment.
That is how x402 becomes agent-readable infrastructure, not just a nicer checkout.
