API Latency Test

OpenAI-compatible relay checker

AI API Relay Health Check

Enter a Base URL and API key. Fetch models, choose one, then run a focused quality test.

No account. API keys are used only for this live test.

What it checks

Model listing, selected model availability, control-question answer, OpenAI-style response shape, streaming quality, latency, TTFT, and rough token speed.

What it cannot prove

This is a practical quality signal, not an absolute audit. Slow, broken, or inconsistent behavior is a warning before you buy or rely on a relay.
