请求参数

model string
模型名称，**固定传 `"flowmusic"`**（大小写不敏感）
clip_id string
源音乐的唯一标识符，来自已成功任务的 `result.music[].clip_id`
instruction string
Cover 编辑指令 示例：`"将这首歌曲改为爵士风格"`
strength number
编辑强度 取值范围：`0` \~ `1`，越大改动越大
title string
Cover 后的音乐标题
seed string
随机种子，用于结果复现

响应

code integer
响应状态码，成功时为 200
data array
返回数据数组 任务状态，初始提交时为 `submitted`
task_id string
任务唯一标识符，用于查询任务状态和结果

使用场景

场景 1：整曲改为爵士风格

{
  "model": "flowmusic",
  "clip_id": "abc123-def456",
  "instruction": "将这首歌曲改为爵士风格",
  "strength": 0.5
}

场景 2：外部音频导入后改编

先通过上传音频把外部音频导入换取 clip_id，再做 Cover：

{
  "model": "flowmusic",
  "clip_id": "1db3a20f-4ddc-44e8-8c9c-6c9093c16ffe",
  "instruction": "改成爵士风格",
  "strength": 0.6
}
注意
**查询任务结果** Cover 改编为异步任务，提交后会返回 `task_id`。使用 [获取任务状态](./query) 接口查询生成进度和结果。Cover 产物是**新的** `clip_id`，后续操作请使用新 clip\_id。
