Query image taskPoll the status and result of an image generation task created via `POST /v1/image-generation`. Call this endpoint periodically with the `task_id` returned from task creation. When `status` is `Success`, `output_images` contains the generated image URLs. **Note:** this endpoint's envelope uses `message`, not `msg` as the create task endpoint does. Plan both field names when parsing. ### Recommended polling schedule Image generation averages ~1 minute (some as fast as 10s). Use this schedule to balance responsiveness and request cost: | Phase | Elapsed | Interval | | --- | --- | --- | | Initial wait | 0 – 10s | — (no requests) | | Dense | 10s – 1 min | every 3s | | Medium | 1 – 3 min | every 6s | | Slow | 3 – 15 min | every 10s | | Timeout | > 15 min | stop, report error | Stop polling when `status` is `Success`, `Failed`, or `Cancelled`.
