## Notes

* Only available for workflows with status `completed`
* Signed URLs are temporary and expire after a set period (typically 5 min)
* Output files include all media generated by ComfyUI SaveImage/SaveVideo nodes
* File formats depend on your workflow configuration (PNG, JPG, MP4, WebP, etc.)
* Download files before the signed URLs expire
* Outputs are stored securely and isolated per user
* Empty array is returned if the workflow completed but generated no outputs
