The catalogue no longer lists any model from this vendor. The last one went on 2026-08-22.
This page is kept as the record. It does not mean the vendor shut down - we watch one catalogue, and a vendor can leave it and still be trading elsewhere.
If a call to one of these ids started failing with a model-not-found error or an HTTP 404, this is the reason - not your API key and not your request.
Everything else that is going away - announced shutdowns and the rest of the silent removals.
Something in your code may still reference a model from this vendor. The same check runs over a whole repository:
curl -sO https://neosignal-ai.vercel.app/check.py
python check.py .
