Decided from what the probe found at the endpoint, and from what each client's own documentation says it can complete. Every row carries the day that documentation was read.

The handshake was refused with no challenge and no OAuth metadata, so what this server wants is not something the probe could record.

How to authenticate
Checked against the endpoint by our probe on 22 Sep 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | Unknown |
|---|---|
| Protected-resource metadata | ✕Not found Without it a client has to guess where the authorization server lives. |
| Anonymous access | Refused — credentials required |
What the probe found
It speaks JSON-RPC but rejected the handshake: {"code":"BACKEND_UNREACHABLE","message":"The evidence service is temporarily unavailable; no payment was taken.","request_id":"req_5a8316c355484918acf1fbcb"}
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.
