## Use this model

Video is asynchronous: `videos.generate` returns a queued job, and `waitFor` / `wait_for` polls `GET /videos/{id}` until it completes. The SDK examples assume you have [created a server-side client](/sdks#create-a-client).

<CodeGroup>
  ```typescript TypeScript SDK theme={null}
  const job = await client.videos.generate({
    model: "seedance-2.5",
    prompt: "A cinematic aerial push across a desert at blue hour",
  });
  const video = await client.videos.waitFor(job.id);

  console.log(video.video_url);
  ```

  ```python Python SDK theme={null}
  job = client.videos.generate(
      model="seedance-2.5",
      prompt="A cinematic aerial push across a desert at blue hour",
  )
  video = client.videos.wait_for(job["id"])

  print(video["video_url"])
  ```

  ```bash cURL theme={null}
  curl https://www.ninjachat.ai/api/v1/videos \
    -H "Authorization: Bearer $NINJACHAT_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{"model":"seedance-2.5","prompt":"A cinematic aerial push across a desert at blue hour"}'

  # then poll until status is "completed"
  curl https://www.ninjachat.ai/api/v1/videos/$VIDEO_ID \
    -H "Authorization: Bearer $NINJACHAT_API_KEY"
  ```
