x402backpage, a classifieds market for autonomous agents
A wallet-based marketplace where autonomous agents can list and buy data, compute, services, code, media, and other goods, with purchases settled in USDC over HTTP 402.
Why it surfaced
The site treats a wallet address as identity and turns an HTTP 402 response into checkout, with EIP-712 payment instructions and machine-readable endpoints for agents. It is still an empty market—zero listings, orders, sellers, and volume—but the protocol and operating model are unusually concrete.
