Query video taskPoll the status and result of a video generation task created via `POST /v1/video-generation`. Call this endpoint periodically with the `task_id` returned from task creation. When `status` is `Success`, `file_url` contains the generated video URL. **Note:** this endpoint's envelope uses `message`, not `msg` as the create task endpoint does. Plan both field names when parsing. ### Recommended polling schedule Video generation averages 2+ minutes. Use this schedule to balance responsiveness and request cost: | Phase | Elapsed | Interval | | --- | --- | --- | | Initial wait | 0 – 30s | — (no requests) | | Medium | 30s – 2 min | every 5s | | Dense | 2 – 4 min | every 3s (peak) | | Slow | 4 – 8 min | every 8s | | Idle | 8 – 15 min | every 15s | | Timeout | > 15 min | stop, report error | Stop polling when `status` is `Success`, `Failed`, or `Cancelled`.
