📌 Step 1: Log in to Cloudflare Workers

Go to Cloudflare Workers and log in to your account.

📌 Step 2: Create a New Worker

In the Cloudflare Workers dashboard, click on "Create a Service" to create a new worker.

📌 Step 3: Copy and Paste the Code into the Worker

// worker.js - Cloudflare Worker Script By - WOODcraft
export default {
  async fetch(request, env) {
    const url = new URL(request.url);
    const models = {
      "realistic_vision": "SG161222/Realistic_Vision_V5.1_noVAE",
      "dreamshaper": "Lykon/DreamShaper-v7",
      "sdxl": "stabilityai/stable-diffusion-xl-base-1.0",
      "deliberate": "XpucT/Deliberate",
      "anything_v5": "stabilityai/stable-diffusion-2-1",
      "protogen": "darkstorm2150/Protogen_x5.8",
      "flux": "black-forest-labs/FLUX.1-dev"
    };

    if (url.searchParams.get("model") === "list") {
      return new Response(JSON.stringify(models, null, 2), {
        headers: { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }
      });
    }

    let modelKey = url.searchParams.get('model') || "realistic_vision";
    let model = models[modelKey] || models["realistic_vision"];
    const prompt = url.searchParams.get('input') || 'A futuristic city at sunset';

    if (!env.HUGGINGFACE_TOKEN) {
      return new Response(JSON.stringify({ error: "Missing Hugging Face API token" }), {
        status: 401,
        headers: { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }
      });
    }

    const requestBody = { inputs: prompt };
    try {
      const response = await fetch(`https://api-inference.huggingface.co/models/${model}`, {
        method: "POST",
        headers: { "Authorization": `Bearer ${env.HUGGINGFACE_TOKEN}`, "Content-Type": "application/json" },
        body: JSON.stringify(requestBody)
      });

      if (!response.ok) {
        const errorResponse = await response.json();
        return new Response(JSON.stringify({ error: "Failed to fetch from Hugging Face API", details: errorResponse }), {
          status: response.status,
          headers: { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }
        });
      }

      const imageBuffer = await response.arrayBuffer();
      return new Response(imageBuffer, {
        headers: { "Content-Type": "image/png", "Access-Control-Allow-Origin": "*" }
      });

    } catch (error) {
      return new Response(JSON.stringify({ error: "Internal Server Error", details: error.message }), {
        status: 500,
        headers: { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }
      });
    }
  }
};

📌 Step 4: Save and Deploy the Worker

Click "Save" and then "Deploy" to make your worker live.

🏞️ Use the model list

You can now use the any model:

 {
  "realistic_vision": "SG161222/Realistic_Vision_V5.1_noVAE",
  "dreamshaper": "Lykon/DreamShaper-v7",
  "sdxl": "stabilityai/stable-diffusion-xl-base-1.0",
  "deliberate": "XpucT/Deliberate",
  "anything_v5": "stabilityai/stable-diffusion-2-1",
  "protogen": "darkstorm2150/Protogen_x5.8",
  "flux": "black-forest-labs/FLUX.1-dev"
}

📌 Step 5: Use the API URL

You can now use the Worker URL to make API calls. Example:

https://your-worker-name.YOUR_SUBDOMAIN.workers.dev/?input=An astronaut on Mars&model=flux

📌 Step 6: Set Up Hugging Face API Token

Follow these steps:

Go to Hugging Face API Tokens
Log in or create an account
Click "New token" and create a token with read access
Copy the token

📌 How to Add the API Token in Cloudflare Workers

Once you have the Hugging Face token, follow these steps:

Open your Cloudflare Worker dashboard
Go to your deployed Worker
Click on Variables (Environment Variables)
Add a new variable: HUGGINGFACE_TOKEN = your_api_token_here
Click "Save and Deploy"
