Why it matters

Your model-serving API answers anyone: strangers can list your models and run unlimited inference on your GPU — you pay the compute bill, and they can read anything the model was prompted with through your app.

What a probe sees

GET :8000/version and GET /v1/models both answer without an API key.

Internet-facing exposure — observable from the public internet with GET-only probes (the same probes unauth.dev sends).

In the wild

No honeypot telemetry for this service yet (in_the_wild: null in the dataset). We do not invent numbers. The block appears when the honeypot has real data.
