X402 Register API
Register an x402 endpoint so agents can find and pay it (x402scan + Coinbase Bazaar). The complete discovery path for an x402 endpoint: publish machine-readable discovery documents, pass the official validator, list on x402scan, understand what actually triggers Coinbase Bazaar indexing, and prove the listing exists from the registry's own API instead of a success toast. Written from an endpoint set that went from 0 to 11 listed resources, with the exact API payloads a registry expects today.
