请求参数

model string

模型名称，固定传 "flowmusic"（大小写不敏感）

prompt string

生成歌词的提示词，≤ 3000 字符

建议描述歌曲主题、风格、情绪等，以获得更贴合的歌词

响应

code integer

响应状态码，成功时为 200

data array

返回数据数组

status string

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：按主题生成歌词

{
  "model": "flowmusic",
  "prompt": "一首关于坚持的摇滚歌曲"
}

场景 2：歌词回填成曲

先生成歌词，完成后取 result.lyrics[0] 的 title 和 lyrics，回填到生成音乐接口：

{
  "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"
}

注意

查询任务结果

歌词生成为异步任务，提交后会返回 task_id。使用获取任务状态接口查询生成进度和结果。
