}將一個可公開存取的來源 URL 匯入至 Seedance 素材群組。TokenLab 會儲存該素材以供後續使用；請使用回傳的素材資產
TokenLab 會檢查來源 URL、媒體類型、檔案大小和可讀取的圖片尺寸。接受匯入不代表素材已就緒：請等待
id 進行生成，而非使用來源 URL。
對於 library_type: "aigc_avatar"，group_id 為選填；TokenLab 將使用或建立組織預設的虛擬人像群組。對於 library_type: "liveness_face"，group_id 為必填，且必須是透過 取得視覺驗證結果 所回傳的 TokenLab 群組。
| 類型 | 支援的輸入 |
|---|---|
| 圖片 | jpeg, jpg, png, webp, bmp, tiff, gif, heic, heif; ≤30 MiB; 寬度和高度 [300, 6000] px; 寬高比 [0.4, 2.5]. |
| 影片 | mp4, mov; ≤200 MiB. |
| 音訊 | aac, wav, mp3; ≤15 MiB. |
ACTIVE，處理失敗時查看 error_message。其他媒體及人臉要求在處理期間驗證。
建立過程為非同步。請輪詢 取得素材資產 直到 status 變為 ACTIVE。對於真人群組，一個群組對應一個已驗證的人員；若上傳包含多張人臉或與已驗證人員不符的人臉，可能會導致失敗。
project_name 用於同一組織內的資源隔離，預設為 default。相關素材群組和素材須使用相同且區分大小寫的值；POST/PUT 在 JSON 請求主體中傳入，GET/DELETE 在查詢參數中傳入。
