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."

Task status and callbacks

For asynchronous tasks, keep the returned taskId. Query GET /api/v1/jobs/recordInfo?taskId=... or provide callBackUrl when creating the task. Only the account that created a task can access it or derive new resources from it.

A timeout can mean the submission was accepted. Inspect the existing request in your dashboard; do not create another task automatically. Callback delivery is retried and may arrive more than once. Deduplicate with X-VezAPI-Event-Id.

Files, logs and billing

Generated media normally follows a 14-day provider lifetime; uploaded files expire after 24 hours. Save the files you need before expiration. VezAPI streams registered files without keeping a permanent media library. Request logs are retained for two calendar months.

Credits are reserved before submission. Final deductions match actual discounted consumption one for one. Unknown usage pauses new paid requests. If available funds cannot cover final usage while protecting other reservations, settlement stays pending until funded; model usage cannot make the wallet negative. Time-based inputs require server-side metadata reads; a failed read prevents submission.
