status

pending: Accepted and waiting to start. Keep polling.
processing: Running. Keep polling.
completed: Finished. Read video_url; output holds the full result.
failed: Ended without a result. error_message says why and credits_refunded shows what was returned.

Poll every 5 to 10 seconds and stop at completed or failed, or register a webhook to be notified instead. Failed tasks are refunded automatically.
