Hello, I am consistently receiving a `404 Not Found` error when trying to use the Inference API, and I believe there is an issue with my account’s permissions. I have confirmed the following through extensive testing: 1. **My API token is correct** and authenticates properly. A diagnostic script confirms this. 2. The error occurs for **all models** I try, including fully public models like `HuggingFaceH4/zephyr-7b-beta` and gated models I have been granted access to, like `mistralai/Mixtral-8x7B-Instruct-v0.1`. 3. The issue is **not network-related**. I have tried from different IP addresses and regions using a VPN, and the result is the same `404 Not Found` error. 4. The issue is **not the request format**. I have also tried adding a standard browser `User-Agent` header to my requests, and the error still persists. It seems there is a specific issue with my account’s fundamental ability to access the Inference API service. Could you please investigate? My Hugging Face username is: **Shkila-coder** Thank you. ---

[Inference API has been revamped into Inference Providers, resulting in significant changes to its specifications and the models that can be used](https://discuss.huggingface.co/t/persistent-404-not-found-error-from-inference-api-on-a-specific-machine/168586/3). [The models currently deployed are these](https://huggingface.co/models?inference_provider=all&sort=trending). ---

Thank you for the clarification, John6666. Following your advice, I switched my code to use a model from the official “Inference Providers” list that you linked: HuggingFaceTB/SmolLM3-3B. Unfortunately, I am still receiving the exact same 404 Not Found error, even with this confirmed-available model. This seems to prove that the issue is not with model selection, but a fundamental problem with my account’s permissions to access the Inference API for any model at all. ---

Hm. Endpoint URLs have also changed, so if you’re referencing old code, [you may need to rewrite it](https://huggingface.co/docs/inference-providers/en/guides/first-api-call). If you’re experiencing account issues, I recommend to contact Hugging Face via email first. [website@huggingface.co](mailto:website@huggingface.co) ---

Hi @Shkila-coder Can you please check to make sure you’re authenticated? You’ll want to make sure you’re using a`fine-grained` token with `Make calls to Inference Providers` permissions. More info here: [Authentication](https://huggingface.co/docs/inference-providers/en/index#authentication). ---

Hello, thank you for the specific instructions. I have now done the following: Deleted all old tokens. Created a new fine-grained token. Gave it the specific permission: “Make calls to Inference Providers” under User Permissions. Unfortunately, I am still receiving the exact same 404 Not Found error when calling the API for a public model from the approved list (HuggingFaceTB/SmolLM3-3B). ---

I can send you the code and my settings if needed.
