Will my client connect?
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.

How to authenticate
Checked against the endpoint by our probe on 31 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | OAuth |
|---|---|
| Issuer | https://chartlink.app/api/auth |
| Dynamic client registration | ✓Advertised (RFC 7591) |
| Client ID Metadata Document | ✕Not advertised |
| PKCE | ✓S256 |
| Grant types | authorization_code, client_credentials, refresh_token |
| Scopes | openid, profile, email, offline_access |
| Protected-resource metadata | ✓Published (RFC 9728) |
| Anonymous access | Refused — credentials required |
What the probe found
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.
Neither the reserved <endpoint>/server-card location nor the domain's /.well-known/ai-catalog.json describes this endpoint (SEP-2127), so a client that discovers servers by domain will not find it.
