## 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.
- `402`: No key and no valid payment. The price and how to pay are in the `PAYMENT-REQUIRED` header; the body says the same in words. A request that sent a key never gets this — it gets `401`/`403` instead.
- `403`: RFC 9457 problem document.
- `404`: Not found. A token that does not decode gets this too.
