Body

application/json

modelstring · enumRequiredPossible values:

promptstring · min: 1 · max: 4000Required

The text prompt describing the content, style, or composition of the image to be generated.

Example: A photorealistic red sports car on a winding coastal road at sunset, cinematic lighting.

aspect_ratiostring · enumOptional

The aspect ratio of the generated image.

Default: 1:1Example: 16:9Possible values:

max_tokensinteger · min: 1Optional

The maximum number of tokens that can be generated. This value can be used to control costs for text generated via API.

Example: 4096

temperaturenumber · max: 2Optional

What sampling temperature to use. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

Default: 1Example: 1

max_completion_tokensinteger · min: 1Optional

An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens.

Quick Example

Let's generate an image using a simple text 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": "microsoft/mai-image-2.5",
            "prompt": "A futuristic city at night with neon lights reflecting on wet streets",
        }
    )

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

if __name__ == "__main__":
    main()
