Summary
This lets you spin up an Express server that charges USDC per API request using the x402 protocol. Instead of managing API keys or subscriptions, clients just pay when they hit your endpoint. You get a 402 response with payment requirements, they sign a USDC transaction on Base, and retry with a payment header. The middleware handles verification through a facilitator service. What's interesting is the automatic discovery piece: register with the x402 Bazaar and other agents can find and pay for your service without any manual integration. Good fit if you're monetizing data or compute and want the payment rails built in rather than bolted on.
