Query Task Status

After submitting a task, use the unified query endpoint to check progress and retrieve results:

Get Task Info

Learn how to query task status and retrieve generation results
For production use, we recommend using the callback_url parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.
