Quick Example

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

The maximum value for both width and height is 1440, and the minimum is 256. The value must be a multiple of 32.

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={
            "prompt": "A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.",
            "model": "flux-pro/v1.1",
            'image_size': {
                "width": 1024,
                "height": 320
            }
        }
    )
    
    data = response.json()
    print(json.dumps(data, indent=2, ensure_ascii=False))

if __name__ == "__main__":
    main()

JS

async function main() {
  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: 'flux-pro/v1.1',
      prompt: 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.',
      image_size: {
        width: 1024,
        height: 320
      },
    }),
  });

  const data = await response.json();
  console.log(data);
}

main();

  ],
  timings: {},
  seed: 1345862631,
  has_nsfw_concepts: [ false ],
  prompt: 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.'
}

We obtained the following 1024x320 image (JPEG) by running this code example:

"A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses."
