## 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.

High top angle wide mid close-up tracking shot, flying
very fast two meters high over prehistoric ferns and
moss-covered ground, dominated by a real young boy (pink
t-shirt, pink shorts, white shoes, white long socks),
with his back to the camera, body stretched out, gliding
smoothly forward, flying in the air, casting a clear
shadow on the terrain below. His legs and body are high
above the surface, his feet not touching the ground,
soaring in a Superman pose. The background is a vast
Jurassic valley, filled with dense, ancient jungle
vegetation and towering cycads. In the distance, rugged
volcanic mountains rise with a winding path cutting
through. Massive, slow-moving sauropods graze far off on
the horizon. Large, fluffy white clouds float in the
vibrant blue sky. Strong dynamic motion blur adds a
vivid sense of high-speed flight and deep cinematic
perspective. Realistic image –raw.
