Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:Get Task Details
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.Related Resources

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
API — Now on Apikley” softly pulses with a golden glow.
The camera pushes forward slightly, then slowly fades to
black.
