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

TIP

For production use, we recommend using the callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.
