  "prompt": "A slow push-in on a lighthouse at dusk, waves breaking below",
  "aspect_ratio": "16:9",
  "duration": "3",
  "model_id": "berry-2"
}' | jq -r '.status_url')

# Repeat until status is "completed"; result.url is the file
curl "$STATUS_URL" --header "Authorization: Bearer $MAGE_API_KEY"
Python
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()

print(request["status"], request["result"] and request["result"]["url"])
JavaScript
const headers = {
  Authorization: `Bearer ${process.env.MAGE_API_KEY}`,

  await new Promise((resolve) => setTimeout(resolve, 3000));
  request = await fetch(request.status_url, { headers }).then((r) => r.json());
}

console.log(request.status, request.result?.url);
