SSE integrity
Check OpenAI-compatible API stream integrity
Inspect SSE structure and streamed model identity for substitution or corruption.
How this check works
A stream integrity check looks at SSE events on an OpenAI-compatible API. It checks event shape and whether the streamed model name still matches the request.
01Probe
Open an SSE stream for a known request.
02Inspect
Check event types, usage, and the streamed model name.
03Conclude
Flag substitution or corruption when the stream no longer matches the request.
- How to read the result
- Final text can look fine after the stream was rewritten. A model-name mismatch in SSE is a stronger identity signal than the last paragraph.
- When to run this check
- Use this if your client reads the stream, not only the final message. Pair it with identity checks for chat apps that show the model name.

FAQ
What is OpenAI-compatible API stream integrity?
It means the SSE events stay well-formed and the streamed model identity still matches the request.
Why inspect the stream instead of the final text?
The final text can look complete after the stream was rewritten. Event types and model names are where substitution often shows up.
Does this check every streaming client?
It checks the SSE surface this endpoint returns. A different client wrapper can still change how events are consumed.
