旧版素材库

旧版模型只能使用本节 /v1/seedance/* 创建的素材。新版 /v1/seedance/v2/* 返回的 ID 不能用于旧版模型。

以下接口均使用：

Base URL: https://www.dianlitoken.com
Authorization: Bearer <API_KEY>

创建素材组

curl -X POST "https://www.dianlitoken.com/v1/seedance/asset-groups" \
  -H "Authorization: Bearer $DIANLI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"角色素材","description":"项目角色参考","group_type":""}'

响应：

{"id":"group_xxx","name":"角色素材","group_type":""}

列出素材组

curl "https://www.dianlitoken.com/v1/seedance/asset-groups" \
  -H "Authorization: Bearer $DIANLI_API_KEY"

{
  "data": [
    {
      "id": "group_xxx",
      "name": "角色素材",
      "group_type": "",
      "source": "manual",
      "created_at": 1787535000
    }
  ]
}

通过公网 URL 创建素材

curl -X POST "https://www.dianlitoken.com/v1/seedance/assets" \
  -H "Authorization: Bearer $DIANLI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "group_id":"group_xxx",
    "url":"https://example.com/character.jpg",
    "name":"角色正面照",
    "asset_type":"Image"
  }'

asset_type 区分大小写，只能是 Image、Video 或 Audio。group_id 可省略，平台会为当前用户创建默认素材组。

响应：

{
  "id": "asset_xxx",
  "group_id": "group_xxx",
  "name": "角色正面照",
  "asset_type": "Image"
}

查询、更新和删除

curl "https://www.dianlitoken.com/v1/seedance/assets/asset_xxx" \
  -H "Authorization: Bearer $DIANLI_API_KEY"

curl -X PATCH "https://www.dianlitoken.com/v1/seedance/assets/asset_xxx" \
  -H "Authorization: Bearer $DIANLI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/character-new.jpg"}'

curl -X DELETE "https://www.dianlitoken.com/v1/seedance/assets/asset_xxx" \
  -H "Authorization: Bearer $DIANLI_API_KEY"

删除成功返回：

{"deleted":true}

在任务中引用

{
  "type": "image_url",
  "image_url": {"url": "asset://asset_xxx"},
  "role": "reference_image"
}

平台会校验素材归属。请保存创建接口返回的 asset_id，不要使用本地路径，也不要把新版素材 ID 填到旧版任务中。
