  "aspect_ratio": "16:9",
  "duration": "3",
  "model_id": "lemon"
}' | jq -r '.status_url')

import os, time, requests

headers = {"Authorization": f"Bearer {os.environ['MAGE_API_KEY']}"}
request = requests.post(

while request["status"] in ("queued", "in_progress"):
    time.sleep(3)
    request = requests.get(request["status_url"], headers=headers).json()
