How do I request it?

One request, one duration value.

import os
import time

import requests

H = {"Authorization": f"Bearer {os.environ['SUME_API_KEY']}"}
job = requests.post(
    "https://api.sume.com/v1/videos",
    headers=H,
    json={
        "model": "wan-3.0",
        "prompt": "A paper boat drifts down a rain-soaked street at dusk",
        "duration": 11,
        "resolution": "720p",
        "aspect_ratio": "16:9",
    },
).json()
while True:
    s = requests.get(job["polling_url"], headers=H).json()
    if s["status"] in ("completed", "failed"):
        break
    time.sleep(10)
print(s["status"], s.get("unsigned_urls"))

What this leaves out

Prices only; no quality ranking.

• Longer single clips can drift more than short ones; check the result before scaling.
• Audio, aspect ratio and reference images can change a job; the table assumes defaults at 16:9.
• Re-read the pricing page before budgeting; rates change.
