## Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:
Learn how to query task status and retrieve generation results
For production use, we recommend using the `callBackUrl` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.

JSON payload containing results
- Alternatively, use the Get Task Details endpoint to poll
task status

Begin with the uploaded image as the first frame.
Gradually animate the scene: steam rises and drifts
upward from the train; lantern lights flicker subtly;
cloaked figures begin to move slowly — walking, turning,
adjusting their belongings. Floating dust or magical
particles catch the light. The text “KLING 2.1 STANDARD

The camera pushes forward slightly, then slowly fades to
black.
