认证

Authorization string

所有接口均需要使用 Bearer Token 进行认证获取 API Key：访问 [API Key 管理页面](https://openveer.com) 获取您的 API Key 使用时在请求头中添加： ``` Authorization: Bearer YOUR_API_KEY ```

请求参数

model string

模型名称，**固定传 `"flowmusic"`**（大小写不敏感）

sound_prompt string

音乐风格或声音描述提示词示例：`"upbeat pop music with piano"`

注意

`sound_prompt` 与 `lyrics` **不可同时为空**（至少传一个）。每次请求仅生成一首音乐。

lyrics string

歌词文本，可先用[生成歌词](./lyrics)接口获得后回填示例：`"[Verse 1]\n黑夜再长也会天亮\n..."`

title string

生成音乐标题

bpm string

BPM（每分钟节拍数），必须 ≥ 1 示例：`"120"`

length integer

生成时长（秒）支持范围：`1` \~ `240` 秒

seed string

随机种子，用于复现结果

注意

相同的请求下传相同的 seed 值，会生成类似的结果，但不保证完全一致。

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：纯风格提示词生成

{
  "model": "flowmusic",
  "title": "My Song",
  "sound_prompt": "upbeat pop music with piano",
  "bpm": "120",
  "length": 60
}

场景 2：歌词 + 风格成曲

{
  "model": "flowmusic",
  "title": "坚持",
  "lyrics": "[Verse 1]\n黑夜再长也会天亮\n...",
  "sound_prompt": "energetic rock with electric guitar",
  "length": 120
}

注意

**查询任务结果** 音乐生成为异步任务，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。
