## 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
::: tip[]
For production use, we recommend using the `callBackUrl` parameter to
receive automatic notifications when generation completes, rather than
polling the status endpoint.
