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.",

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.
