}提交一个可公开访问的文件 URL，TokenLab 会将它保存到 Seedance 素材组。后续生成使用返回的素材
TokenLab 会检查来源 URL、媒体类型、文件大小和可读取的图像尺寸。导入受理不代表素材已就绪：请等待
id。
library_type: "aigc_avatar" 可以省略 group_id，素材会进入工作区的默认素材组。library_type: "liveness_face" 必须传入 视觉验证结果 返回的素材组 ID。
| 类型 | 支持的输入 |
|---|---|
| 图像 | jpeg, jpg, png, webp, bmp, tiff, gif, heic, heif; ≤30 MiB; 宽度和高度 [300, 6000] px; 宽高比 [0.4, 2.5]. |
| 视频 | mp4, mov; ≤200 MiB. |
| 音频 | aac, wav, mp3; ≤15 MiB. |
ACTIVE，处理失败时查看 error_message。其他媒体及人脸要求在处理期间校验。
素材需要一些时间处理。通过 获取素材 查询状态；status 变为 ACTIVE 后即可使用。真人素材组只对应一位已验证人员，图片中出现多张人脸或人员不一致时会处理失败。
project_name 用于同一组织内的资源隔离，默认为 default。相关素材组和素材须使用相同且区分大小写的值；POST/PUT 在 JSON 请求体中传入，GET/DELETE 在查询参数中传入。
