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 Tngtech, not just a compatible protocol.
- Then list models or run a lightweight probe: check whether models like DeepSeek R1T2 Chimera are visible and return stable evidence.
- Finally record 400/502, error body, latency, egress IP, and reproducibility to separate balance, permission, route, or upstream issues.
Next action
streaming failed 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.
