Hi @simpx,
HF_ENDPOINT env variable is already used by default to construct the API URLs when interacting with the Hugging Face Hub. I'm closing this PR as there's no need to manually read and pass this environment variable to the function.

If you want to customize the base URL used to interact with the Hugging Face Hub, You can set the HF_ENDPOINT environment variable before downloading:

export HF_ENDPOINT="your-custom-endpoint"
huggingface-cli download [repo_id] [filenames]
