Quick Example

Let's generate an image using a simple prompt.

import requests
import json

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": "hunyuan/hunyuan-image-v3-text-to-image",
            "image_size": "landscape_16_9"
        }
    )

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

if __name__ == "__main__":
    main()
Response
{
    "data": [
        {
            "url": "https://v3b.fal.media/files/b/lion/JdrvNguTlt29LmURRbKKN.png",
            "content_type": "image/png",
            "file_name": null,
            "file_size": null,
            "width": 1280,
            "height": 768
        }
    ],
    "meta": {
        "usage": {
            "tokens_used": 210000
        }
    }
