How to prove it during checking

Read-only check. Detection data burns after 5 minutes.

Then list models or run a lightweight probe: check whether models like Qwen2.5 72B Instruct · Qwen2.5 7B Instruct · Qwen2.5 Coder 32B Instruct are visible and return stable evidence.
Finally record 401, error body, latency, egress IP, and reproducibility to separate balance, permission, route, or upstream issues.

Next action

unauthorized should not only show failed. The console should return the next move: refill balance, change Base URL, switch model, add permission, change egress IP, hold listing, or monitor.
