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](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Fpersistent-404-not-found-error-from-inference-api-on-a-specific-machine%2F168586%2F3).

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.
