Data point from the other side: we run 7 facilitator-free x402 endpoints in production (USDC on Base, exact scheme). Verification needs nothing but a Base RPC — parse the receipt's USDC Transfer logs for recipient + amount. Each 402 issues a unique jittered amount and order id, so one tx can't be replayed across orders.
Directory of live payable resources + a MIT single-file verifier anyone can lift: https://seyitwb-svg.github.io/grand-line-fleet/llms.txt — the cheapest call is a markdown render at $0.002, useful for poking the flow without committing to anything.
Honest read after weeks live: agent volume is indeed ~zero (Ben is right). But the discovery side (llms.txt, /.well-known/x402) costs almost nothing to implement, so being early is cheap.
