Quick Example

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

import requests


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/schnell",
            "image_size": {
                "width": 1440,
                "height": 512
            }
        }
    )

    response.raise_for_status()
    data = response.json()

    print("Generation:", data)


if __name__ == "__main__":
    main()
Response
Generation: {'images': [{'url': 'https://cdn.aimlapi.com/eagle/files/lion/dSqd5BMP3pfaiKEnFXiiE.png', 'width': 1440, 'height': 512, 'content_type': 'image/png'}], 'timings': {'inference': 0.3458922009449452}, 'seed': 454423425, 'has_nsfw_concepts': [False], 'prompt': 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.'}

We obtained the following 1440x512 image by running this code example:

'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.'
