How settlement works

A four-step handshake, end to end

Built on @x402/express, with payment verification routed through a wrapped facilitator client for Base and Solana settlement.

Request

402 Required

Server replies with price, chain, and asset — no booking held yet.

Pay

Agent signs a USDC transfer from its wallet, no card or checkout form.

Confirmed
