Hello NVIDIA Team,

I’m experiencing the same issue with the Cosmos3 Nano hosted API.

I generated a valid NVIDIA Build API key and successfully tested the Nemotron API (HTTP 200).

However, requesting Text-to-Video using the endpoint documented in the Cosmos3 Nano model card returns:

HTTP 404 — page not found

Endpoint:
POST https://ai.api.nvidia.com/v1/cosmos/nvidia/cosmos3-nano

Could you confirm whether this hosted endpoint is currently operational, whether additional account permissions are required, or whether a different invocation URL should be used?

Thank you.
