}能力按服务端配置逐项启用。未启用操作返回 503 且不创建任务；音乐积分扣除当前未启用。
调用步骤
指定歌曲中的一段时间，用新歌词或风格重写这一段。-
- 按下方示例准备输入，将占位地址和 ID 换成你有权使用的资源。
-
- 将 model 设为 suno_replace_section，参数放在 input 内。提交一次并保存返回的 task_id。
-
- 查询已保存的任务，或接收回调。任务仍在处理中时继续等待，不重新提交同一操作。
- 从 result.data.data 读取作品。每首歌曲都有独立的本站 id，后续任务可将其作为 audio_id。
创建任务
将model和input发送到统一任务入口；可在顶层传公开HTTPS callback_url。资源ID均为本账户的本站ID。当前音乐积分扣除未启用。{
"model": "suno_replace_section",
"input": {
"audio_id": "YOUR_AUDIO_ID",
"prompt": "[Verse] A new beginning",
"tags": "Pop",
"title": "New verse",
"infill_start_s": 20,
"infill_end_s": 40,
"full_lyrics": "Original full lyrics"
}
}
受理响应
HTTP 200仅表示受理。查询GET /api/v1/tasks/{task_id}，直到data.status为succeeded或failed。成功后读取data.result；失败原因位于data.message。{
"code": 200,
"msg": "success",
"data": {
"task_id": "YOUR_TASK_ID"
}
}

重要条件
- 替换区间必须位于原曲内，至少10秒、最多120秒，且不超过原曲时长的一半；起止位置最多两位小数。prompt仍然必填；lyrics仅覆盖替换段歌词，full_lyrics为替换后的完整歌曲歌词。
- Persona替换尚未开放；传persona_id返回HTTP 422/code 42201。
- full_song/mixed等待合并，segment/stem返回对应片段或器乐轨。合并失败不会把片段作为完整歌曲返回；部分成功会在结果消息中说明。
- 歌曲音频可能为MP3或M4A；需要真正MP3时使用suno_export_mp3。可选封面无法获取时可能为null，不影响音频使用。
- 上传文件保留24小时，生成文件保留14天，任务详情保留30天；复用文件沿用原到期时间。有效Voice/Persona身份映射与任务日志清理分开处理，请及时下载需长期保存的文件。

歌曲duration单位为秒，任务duration单位为毫秒；createTime是毫秒Unix时间戳或null。目前stream_audio_url和source_stream_audio_url均为null；source_audio_url/source_image_url与audio_url/image_url指向同一本站托管副本，并非供应商直链。请遍历实际歌曲数组，注册上传音频不代表新生成两首歌曲。
