Giving AI Agents a Wallet
summary
A working HTTP payment loop appears: HTTP 402 returns structured metadata, the client signs an EIP‑3099 authorization, a facilitator submits an on‑chain USDC transfer and returns a proof, request retries and the resource is delivered. Implementation uses X402 with exact and up‑to schemes, an MCP CLI demo with a hot wallet (≈$6) shows $1 buys ~400 Instagram profiles, refunds or caps prevent runaway spend, and facilitator settlement completes in seconds on EVM chains.
