Quick Example

Let's generate an image of the specified size using a simple prompt.

Python

import requests
import json  # for getting a structured output with indentation

def main():
    response = requests.post(
        "https://api.aimlapi.com/v1/images/generations",
        headers={
            # Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
            "Authorization": "Bearer <YOUR_AIMLAPI_KEY>",
            "Content-Type": "application/json",
        },
        json={
            "model": "alibaba/qwen-image-2-0",
            "prompt": "Combine the images so the dino is wearing a business suit, sitting in a cozy small café, drinking from the mug. Blur the background slightly to create a bokeh effect.",
            "image_urls": [
                "https://raw.githubusercontent.com/aimlapi/api-docs/main/reference-files/t-rex.png",
                "https://raw.githubusercontent.com/aimlapi/api-docs/main/reference-files/blue-mug.jpg"
            ],
            "image_size": "landscape_4_3"
        }
    )

    data = response.json()
    print(json.dumps(data, indent=2, ensure_ascii=False))

if __name__ == "__main__":
    main()

JS

const response = await fetch('https://api.aimlapi.com/v1/images/generations', {
  method: 'POST',
  headers: {
    // Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
    'Authorization': 'Bearer <YOUR_AIMLAPI_KEY>',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'alibaba/qwen-image-2-0',
    prompt: 'Combine the images so the dino is wearing a business suit, sitting in a cozy small café, drinking from the mug. Blur the background slightly to create a bokeh effect.',
    image_urls: [
      'https://raw.githubusercontent.com/aimlapi/api-docs/main/reference-files/t-rex.png',

    ],
    image_size: 'landscape_4_3'     
  }),
});

const data = await response.json();
console.log(JSON.stringify(data, null, 2));
