Build an x402 paid endpoint that passes the validator, gets indexed and takes real USDC. End-to-end recipe for turning any HTTP capability into an x402 endpoint that an unknown agent can find, pay for and consume: the payment gate, the verifier rules, per-route pricing, the concurrency traps, the nginx wiring, the discovery surface, plus the money-path bugs we only found when real USDC moved. Comes with the exact commands we run.Overview
