Hi Team,

I’m having an issue with the Inference API. I consistently receive a `404 Not Found` response for every model I try, including public models like `gpt2` and even when using a brand new API token with “read” permissions.

I have already confirmed the following:

- My server has a successful network connection to `api-inference.huggingface.co`.
- My API key is being correctly passed in the “Authorization: Bearer” header.

Here is the verbose output from a `curl` test. The request ID for one of the failed attempts is `Root=1-69079074-1aee8cc64f9e26267e2d96a5`.

Note: Unnecessary use of -X or --request, POST is already inferred.

- Host [api-inference.huggingface.co:443](http://api-inference.huggingface.co:443) was resolved.

Could you please check if there are any blocks, limits, or other issues with my account that might be causing this strange `404` error?

That endpoint is for the legacy version of the Inference API and is now deprecated. [The Inference API has been revamped into Inference Providers, with changes to usage and models](https://discuss.huggingface.co/t/401-but-my-api-key-should-be-valid/169191/5). For details, refer to the documentation.

I’ll add to @John6666’s reply by mentioning our guide for making your first API request with Inference Providers: [Your First Inference Provider Call](https://huggingface.co/docs/inference-providers/en/guides/first-api-call).

You can also [Build Your First AI App](https://huggingface.co/docs/inference-providers/en/guides/building-first-app) and [Build an Image Editor](https://huggingface.co/docs/inference-providers/en/guides/image-editor) with Inference Providers too 🤗
