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/kontext-max/text-to-image",
            "aspect_ratio": "21:9"   
        }
    )

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

    print("Generation:", data)


if __name__ == "__main__":
    main()
Response
Generation: {'images': [{'url': 'https://cdn.aimlapi.com/squirrel/files/elephant/zFx0xcGvgRWPYCEqnWseI_69818c90b08d406d874ca470c4b67957.jpg', 'width': 1568, 'height': 672, 'content_type': 'image/jpeg'}], 'timings': {}, 'seed': 1661789076, 'has_nsfw_concepts': [False], 'prompt': 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.'}

We obtained the following 1568x672 image by running this code example:

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