Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | No auth |
|---|---|
| Protected-resource metadata | ✕Not found Without it a client has to guess where the authorization server lives. |
| Anonymous access | Handshake succeeds; 22 tools listable |

What the probe found
4 of the 22 tools listed anonymously say in their own descriptions that they need an account or a key (search, get_article, pay_and_read, answer), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.
A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.
