简介

在素材组内创建素材。Content-Type: application/json，仅支持公网 https URL（BytePlus 须能直接拉取），不支持 Base64 / Data URI / multipart 直传。本地文件请先上传至 OSS / TOS / S3 等对象存储。虚拟（aigc）与真人（liveness_face）素材库均支持 Image / Video / Audio。创建后 status 为 pending，轮询至 active（通常 1~3 分钟）后再用于 asset://。

火山方舟 CreateAsset 自 2026 年起已下线 Base64 直传。详见 Create an Asset。

认证

string

必填

Bearer Token，如 Bearer sk-xxxxxxxxxx

请求参数

string

必填

公网 https 资源地址；网关原样透传给上游

string

必填

素材组 ID（来自创建素材组或创建素材组（真人））

string

默认值:"Image"

Image / Video / Audio，大小写不敏感

string

素材名称（≤ 64 字符，仅用于展示与列表搜索，不参与模型推理）

格式与大小约束

图片 (`Image`)

项目	限制
格式	jpeg / png / webp / bmp / tiff / gif / heic / heif
大小	< 30 MB
长宽比	0.4 ~ 2.5
宽高	300 ~ 6000 px

视频 (`Video`)

项目	限制
格式	mp4 / mov
大小	≤ 50 MB
分辨率	480p、720p（不支持 1080p+）
时长	2 ~ 15 秒
FPS	24 ~ 60
长宽比	0.4 ~ 2.5
宽高	300 ~ 6000 px
总像素（W×H）	409600 ~ 927408

音频 (`Audio`)

项目	限制
格式	mp3 / wav
大小	≤ 15 MB
时长	2 ~ 15 秒

网关仅做 URL 后缀校验；尺寸/时长等由 BytePlus 异步完成，不达标时 status 变为 failed。

请求示例

图片、视频、音频请求体结构相同，仅 asset_type 与 URL 不同：

# 图片
curl -X POST "https://api.tennda.ai/v1/assets" \
  -H "Authorization: Bearer sk-xxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://your-cdn.com/portrait.jpg","group_id":"group-xxx","asset_type":"Image","name":"portrait.jpg"}'

# 视频
curl -X POST "https://api.tennda.ai/v1/assets" \
  -H "Authorization: Bearer sk-xxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://your-cdn.com/dance.mp4","group_id":"group-xxx","asset_type":"Video","name":"dance.mp4"}'

# 音频
curl -X POST "https://api.tennda.ai/v1/assets" \
  -H "Authorization: Bearer sk-xxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://your-cdn.com/voice.mp3","group_id":"group-xxx","asset_type":"Audio","name":"voice.mp3"}'

响应示例

{
  "virtual_id": "asset-20260508120145-pqwhc",
  "asset_url": "asset://asset-20260508120145-pqwhc",
  "group_id": "group-20260508120000-abcde",
  "asset_type": "Image",
  "status": "pending"
}

字段	说明
`asset_url`	视频生成时在 `content` 中引用（按 `asset_type` 映射字段）
`status`	`pending` → `active` / `failed`

下一步：列出素材或查询单个素材轮询状态。
