How to prove it during checking

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

Run read-only identity first: confirm whether the key really belongs to Undi95, not just a compatible protocol.
Then list models or run a lightweight probe: check whether models like ReMM SLERP 13B 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

signature invalid 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.
