## Other responses

- `401`: No key, or a key we do not know. `WWW-Authenticate: Bearer` on the MCP surface. The MCP server needs no key at all; a REST demo key is one click away. On the two x402 routes a request with no key gets `402` instead, with the price.
- `403`: The key is revoked or not yet active, or — on a demo key — the path is outside the demo tier. The detail says which, and carries the upgrade path.
- `404`: RFC 9457 problem document.
