Seedance 2.0 创建素材

这个接口把一个公网素材 URL 注册到素材库，并返回后续视频生成可引用的素材 ID。

使用异步处理模式，创建后返回素材 ID 和 Processing 状态
通过 assetType 区分图片、视频和音频素材
创建成功后可用 GET /api/asset/get 查询素材是否变为 Active
生成视频时可把 Result.Id 拼成 asset://{asset_id}，用于首帧、尾帧、参考图、参考视频或参考音频字段

assetType 枚举怎么理解

assetType 用来告诉接口：这个 url 应该按哪种素材处理。你只需要传一个 url，不需要自己传 imageUrls、videoUrls 或 audioUrls。

`assetType`	含义	等价素材列表	常见用途
`image`	图片素材	`imageUrls: [url]`	首帧图、尾帧图、参考图
`video`	视频素材	`videoUrls: [url]`	参考视频、镜头运动参考
`audio`	音频素材	`audioUrls: [url]`	背景音乐、参考音频

例如你传入：

{
  "url": "https://example.com/assets/camera-motion.mp4",
  "assetType": "video"
}

它表达的含义是：https://example.com/assets/camera-motion.mp4 是一个视频素材，等价于把这个地址放进视频素材列表：

{
  "videoUrls": ["https://example.com/assets/camera-motion.mp4"]
}

同理，如果 assetType 是 image，同一个 url 会按图片素材处理；如果是 audio，同一个 url 会按音频素材处理。

素材 ID 与引用 URI

素材创建成功后，响应里的 Result.Id 是素材 ID，例如 asset-20260528143012-a8x7k。这个值有两种用法：

场景	写法	示例
查询素材状态	直接使用素材 ID	`GET /api/asset/get?id=asset-20260528143012-a8x7k`
在视频生成里引用素材	加上 `asset://` 前缀	`"first_image": "asset://asset-20260528143012-a8x7k"`

asset://asset-20260528143012-a8x7k 表示“引用素材库中这个 ID 对应的素材”。它不是公网 URL，不能直接在浏览器中打开；如果需要查看素材原始地址或当前状态，使用查询素材。常见写法：

{
  "model": "doubao-seedance-2-0-260128",
  "prompt": "让首帧图中的人物自然转身，看向镜头",
  "duration": 6,
  "aspect_ratio": "9:16",
  "first_image": "asset://asset-20260528143012-a8x7k"
}

多参考素材也使用同样的 URI 写法：

{
  "reference_image_urls": ["asset://asset-20260528143012-a8x7k"],
  "reference_video_urls": ["asset://asset-20260528143708-k9m2p"],
  "reference_audio_urls": ["asset://asset-20260528144123-r4s6n"]
}

响应示例

{
  "ResponseMetadata": {
    "Action": "seedance2"
  },
  "Result": {
    "Id": "asset-20260528143012-a8x7k",
    "Name": "product-reference.png",
    "URL": "https://example.com/assets/product-reference.png",
    "AssetType": "image",
    "Status": "Processing"
  }
}

{
  "error": {
    "message": "invalid character '}' looking for beginning of object key string",
    "type": "invalid_request_error"
  }
}

{
  "error": {
    "message": "无效的令牌",
    "type": "invalid_request_error"
  }
}

{
  "error": {
    "message": "余额不足",
    "type": "insufficient_quota"
  }
}

{
  "error": {
    "message": "rate limit exceeded",
    "type": "rate_limit_exceeded"
  }
}

{
  "error": {
    "message": "url is required",
    "type": "do_request_failed"
  }
}

认证

Authorization: Bearer YOUR_API_KEY

Body

string

required

素材公网 URL。必须是服务端可访问的地址，例如 https://example.com/assets/product-reference.png。

string

素材名称。建议传入带扩展名的文件名，例如 product-reference.png、camera-motion.mp4 或 background-music.mp3。

string

素材类型。支持 image、video、audio；未传时按 image 处理。建议始终显式传入，避免视频或音频 URL 被当作图片素材。

Response

object

请求元信息。Seedance 2.0 素材接口通常会返回 Action。

string

素材 ID，例如 asset-20260528143012-a8x7k。查询素材时直接传这个 ID；在视频生成请求中引用素材时写成 asset://asset-20260528143012-a8x7k。

string

素材名称。通常来自请求里的 name。

string

原始素材 URL。

string

素材类型，通常与请求里的 assetType 一致。

string

素材状态。常见值为 Processing、Active、Failed。

使用场景

创建参考图片素材

把商品图、角色图、场景图等注册为 image 素材，后续在视频生成请求中作为首帧、尾帧或参考图使用。

{
  "url": "https://example.com/assets/character.png",
  "name": "character.png",
  "assetType": "image"
}

创建参考视频素材

把一段镜头运动、构图或动作参考注册为 video 素材，后续作为参考视频使用。

{
  "url": "https://example.com/assets/motion-reference.mp4",
  "name": "motion-reference.mp4",
  "assetType": "video"
}

创建参考音频素材

把背景音乐、口播或氛围音注册为 audio 素材，后续作为参考音频使用。

{
  "url": "https://example.com/assets/theme.mp3",
  "name": "theme.mp3",
  "assetType": "audio"
}

注意事项

/api/asset/createMedia 只接收一个 url；不要把 imageUrls、videoUrls、audioUrls 直接作为请求字段传入。
assetType 是大小写敏感的公开参数，推荐使用小写的 image、video、audio。
创建成功只代表素材任务已提交。使用前建议调用查询素材确认 Result.Status 已变为 Active。
查询素材时使用裸素材 ID，例如 asset-20260528143012-a8x7k；视频生成字段中引用素材时使用 asset://asset-20260528143012-a8x7k。
如果素材 URL 无法访问、下载超时或格式不被上游接受，素材状态可能变为 Failed。
