For face selection and error recovery, follow Task lifecycle. MCP uses the normalized taskId argument in get_task_result, including capabilities whose REST identifier is requestId.
Credits
| Component / option | Rate | Minimum |
|---|---|---|
| 480p | 10 credits / second | — |
| 720p | 15 credits / second | — |
| 1080p | 30 credits / second | — |
Base charge = duration × the selected resolution rate.
Including reference video adds a flat charge: 480p: 50 credits; 720p: 75 credits; 1080p: 150 credits.
