歌词时间轴

- 生成逐句对齐的歌词时间轴。

  • 生成逐句对齐的歌词时间轴。
  • 引用源音轨：task_id + audio_index 指定，无需记录任何额外 id
  • 异步任务：提交返回 task_id，轮询 GET /v1/music/tasks/:task_id 获取结果
信息
**引用源音轨**：基于已有歌曲的操作无需记任何额外 id，只需传 `task_id`（产出源音轨那次任务的 task\_id）+ `audio_index`（结果 `music[]` 里第几首，1-based，默认 `1`）。
注意
本端点**无版本维度**：不要传 `version`——传了会被丢弃、也不影响计费。

请求示例

Authorizations

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 ```

Body

model string
音频模型。当前传 `suno`（不传默认 `suno`）。
task_id string
产出源音轨那次任务的 `task_id`。缺失或无法解析源时提交期直接返回 `400`。
audio_index integer
引用源任务结果 `data.music[]` 中的第几首（1-based；默认 `1`；一次生成通常 2 首：索引 1 与 2）。
注意
**获取结果**：本接口为异步任务。提交后拿到 `task_id`，按 3–5s 间隔轮询 `GET /v1/music/tasks/{task_id}`，直到 `status` 为 `completed` 或 `failed`（通常 30–120s；生成中 `status` 为 `pending`，`progress` 排队 10 → 就绪 50 → 完成 100）。结果里含带时间戳的歌词。失败时 `data.error.message` 给出原因，且预扣额度自动退回。

Response

code integer
响应状态码
data array
返回数据数组 任务状态 * `submitted` - 已提交
task_id string
任务唯一标识符（用于轮询 `GET /v1/music/tasks/{task_id}` 获取结果）
