API reference

Two auto-generated references land here:

• The x402 wire contract — rendered from x402types/openapi.yaml, the same schema that generates the Go types and the SDKs. Every type is referenced from that file, never copied, so a field change there re-renders here with no manual edit. Zero hand-maintenance.
• The gateway /v1 REST surface (agents, proxy, invocations, analytics, credentials, settlement config) — rendered from gateway/openapi.yaml, the canonical contract hand-authored from the gateway’s HTTP handlers. Adding or altering an endpoint there re-renders here with no manual edit.

Both are wired directly to their canonical schemas — no hand-copied endpoints or types. A CI drift-guard fails the build if either schema changes without its rendered reference regenerating cleanly against it — see the check-www context in .github/workflows/ci.yml.
