## Quick Example

Let's generate an image using two input images and a prompt that defines how they should be edited.

{% tab title="Python" %}

```python
import requests
import json

def main():
    response = requests.post(
        "https://api.aimlapi.com/v1/images/generations",

    )

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