Been trying to make a successful request but everything I try returns a 404 error.

Any advice is appreciated.

```auto
router.get("/test-huggingface-debug", async (req, res) => {
  try {
    // Get API key
    const hugKey = [apiKeyHere];
    if (!hugKey) {
      return res.status(500).json({
        success: false,
        error: "Hugging Face API key not configured",
      });
    }

    console.log(`API Key loaded, starting with: ${hugKey.substring(0, 3)}..., length: ${hugKey.length}`);

    // Use the simplest, most reliable API format with a guaranteed available model
    console.log("Attempting direct API call with fetch...");
    
    // Build the URL and options manually
    const url = "https://api-inference.huggingface.co/models/gpt2";
    const options = {
      method: "POST",
      headers: {
        Authorization: `Bearer ${hugKey}`,
        "Content-Type": "application/json"
      },
      body: JSON.stringify({ inputs: "Hello, I am testing the Hugging Face API." })
    };
    
    // Use native fetch API instead of axios
    console.log("Sending request to:", url);
    const response = await fetch(url, options);
    console.log("Response status:", response.status);
    
    if (!response.ok) {
      const errorText = await response.text();
      console.error("Error response body:", errorText);
      throw new Error(`API responded with status ${response.status}: ${errorText}`);
    }
    
    const data = await response.json();
    console.log("Success! HF Response:", JSON.stringify(data).substring(0, 200));

    return res.status(200).json({
      success: true,
      message: "Successfully connected to Hugging Face API",
      data: data
    });
  } catch (error) {
    console.error("Test HF error:", error.message);
    
    return res.status(500).json({
      success: false,
      error: `Failed to connect to Hugging Face: ${error.message}`
    });
  }
});

```

It seems that the specifications have changed and it no longer works.
