Quick Example

Let's generate an image of the specified size using a simple 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": "bytedance/seededit-3.0-i2i",
            "image": "https://raw.githubusercontent.com/aimlapi/api-docs/main/reference-files/t-rex.png",
            "prompt": "Add a bird to the foreground of the photo.",
        }
    )

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