# 音视频字幕 API（简化版）

## 概述
- 功能：提交音/视频生成字幕任务，并查询字幕结果
- 扣费：在“查询成功返回”时按时长扣积分（VIP也扣）
- 去重：同一 `volcano_task_id` 仅扣一次

## 鉴权
- Header：`x-token: <用户登录令牌>`
- 所有接口需登录态

## 计费与积分
- 换算：`1分钱 = 2积分` → `1元 = 200积分`
- 阶梯单价（按当月累计小时数选择单价）：
  - 0～300 小时：6.5 元/小时 → 1300 积分/小时
  - 301～1000 小时：6 元/小时 → 1200 积分/小时
  - 1001～3000 小时：5.6 元/小时 → 1120 积分/小时
  - 3001～5000 小时：5 元/小时 → 1000 积分/小时
  - 5001+ 小时：4 元/小时 → 800 积分/小时
- 扣费时机：查询成功（`code=0`/`message=Success`）且解析到时长后扣费
- 时长解析顺序：
  - `data.duration`（单位秒，优先）
  - `data.utterances` 的 `start_time`/`end_time`（单位毫秒，取整段范围，换算为秒）
  - 兼容旧格式：`result.duration`、`result.segments`、`result.subtitles`
- 扣减优先级：`FreePoints` → `VipPoints` → `Points`
- 去重规则：积分流水 `reason` 前缀为 `视频字幕生成 volcano_task_id=<id>` 的记录存在即视为已扣
