I’m getting a consistent HTTP 404 error on every POST /v1/chat/completions call, regardless of which model I use. The same API key works fine for GET /v1/models (returns HTTP 200 with the full catalog), so the key itself and network connectivity are not the issue. Account ID: 09kLOjqUWNh9x2WKtefdcJeWuiWamOsdvRIOzimXT6w API key prefix: nvapi-vPNI-... Endpoint: https://integrate.api.nvidia.com/v1/chat/completions Models tested (all fail identically): moonshotai/kimi-k2.6 nvidia/llama-3.1-nemotron-70b-instruct Example request: curl -i --max-time 15 "https://integrate.api.nvidia.com/v1/chat/completions" \ -H "Authorization: Bearer $NVIDIA_API_KEY" \ -H "Content-Type: application/json" \ -d '{"model": "moonshotai/kimi-k2.6", "messages": [{"role":"user","content":"hi"}]}' Response: {"status":404,"title":"Not Found","detail":"Function '23d4f03a-b8a6-4adb-a183-7daa083a09cc': Not found for account '09kLOjqUWNh9x2WKtefdcJeWuiWamOsdvRIOzimXT6w'"} Both models appear correctly in GET /v1/models and work in the build.nvidia.com web playground under the same account. This matches the pattern described in other recent threads on this forum, where the root cause was reported to be the “Public API Endpoints” permission not being enabled for a personal/newly-created organization. Could you please check whether this permission is enabled for my account, and enable it if not? Thanks in advance.

Hi NVIDIA team, I’m experiencing the exact same issue reported in this thread. Adding my details as another instance of this problem: Error: Connection failed: Function '23d4f03a-b8a6-4adb-a183-7daa083a09cc': Not found for account '4u2Kn1CAhTIeGjIxtWz0ClMm5mLjcxm1L7VY5OKFsRM' Details: Endpoint: https://integrate.api.nvidia.com/v1/chat/completions Model: moonshotai/kimi-k2.6 Account ID: 4u2Kn1CAhTIeGjIxtWz0ClMm5mLjcxm1L7VY5OKFsRM The /v1/models endpoint lists the model correctly, but POST /v1/chat/completions fails with a 404 on every request. The same model works fine in the build.nvidia.com playground for this account. For comparison, a separate API key generated for another model (z-ai/glm-5.2) on the same account works without any issue in the same client setup — only the key/model generated from https://build.nvidia.com/moonshotai/kimi-k2.6 fails. I generated the Kimi API key directly from https://build.nvidia.com/moonshotai/kimi-k2.6. This looks like the same “Public API Endpoints” entitlement issue described elsewhere in this thread. Could someone please check the entitlement/deployment mapping for this specific model on my account, or enable Public API Endpoints for it? Thanks in advance for your help.

I have exactly the same issue. My API key is active, GET /v1/models works, but every POST /v1/chat/completions request returns 404 Function not found for account. The NVIDIA Playground works. Please check my account’s Public API Endpoints access.
