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": "x-ai/grok-2-image",
            "prompt": "A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses."
        }
    )

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

if __name__ == "__main__":
    main()

JS

async function main() {
  const response = await fetch('https://api.aimlapi.com/v1/images/generations', {
    method: 'POST',
    headers: {
      // Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
      'Authorization': 'Bearer <YOUR_AIMLAPI_KEY>',
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      model: 'x-ai/grok-2-image',
      prompt: 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.',
    }),
  });

  const data = await response.json();
  console.log('Generation:', data);
}

main();

      "revised_prompt": "A high-resolution photograph of a T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses. The T-Rex is facing slightly to the right, with its sunglasses clearly visible. The background features a calm ocean and a few palm trees, set during the day with natural, soft lighting. The beach is relatively empty, focusing attention on the T-Rex. There are no distracting elements like birds or other animals, ensuring the T-Rex remains the central figure in the composition. The overall mood is serene and tranquil, emphasizing the unusual yet peaceful scene."
