Response {% code overflow="wrap" %} ```json5 { images: [ { url: 'https://cdn.aimlapi.com/eagle/files/panda/tI_UTxAzqLqWZZqSoNqsO_output.png', content_type: 'image/png', file_name: 'output.png', file_size: 1665805 } ], seed: 3360388064 } ``` {% endcode %}
So we obtained the following 1408x768 image by running this code example:

In reality, raccoons shouldn’t be given ice cream or chocolate—it’s harmful to their metabolism.
But in the AI world, raccoons party like there’s no tomorrow.
