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

What the probe found
The server exposes a public surface before authorization: account_register, account_status, billing_upgrade, profiles_manage, accounts_manage, posts_publish, posts_manage, media_pipeline, inbox_messages, comments_moderate, analytics_query, ads_campaigns, blogs_publish, telecom_numbers, telecom_messaging, traffic_analytics.
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.
