What is a machine-payment rail?

The rules, asset, network and verifier that let software settle without a checkout page.

x402 on Base USDC, Stripe/Tempo MPP, and Visa Intelligent Commerce are different rails. They all try to let a machine pay. They do not share one payload.

Choose a rail because your counterparty accepts it and your rights/settlement story is clean — not because a thread was loud.
