# 获取视频字幕异步任务结果/Get video captions async job result

`GET /api/v1/youtube/web_v2/get_video_captions_result`

## Request

- Base URL: `https://api.tikhub.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.tikhub.io/api/v1/youtube/web_v2/get_video_captions_result`
- Auth: HTTP bearer

# [中文]
### 用途:
- 查询字幕异步任务的处理结果
- 视频较大时 `/get_video_captions` 会返回 `status="processing"` 和 `job_id`，
  用该 `job_id` 调用本接口即可获取最终字幕
- 本接口为单次查询、不阻塞等待，由调用方按需重复调用直到任务完成

### 参数:
- job_id: 异步任务ID（由 `/get_video_captions` 返回）
- format: 字幕格式（仅任务完成时生效）
  - srt: SubRip 字幕格式（带时间轴）
  - xml: XML 格式
  - json3: JSON 格式
  - txt: 纯文本（无时间轴）

### 返回数据:
#### 处理中:
```json
{ "job_id": "123e4567-e89b-12d3-a456-426614174000", "status": "queued" }
```
- status 为 `queued`（排队中）或 `active`（处理中），稍后重试即可

#### 已完成:
```json
{
  "job_id": "123e4567-e89b-12d3-a456-426614174000",
  "status": "completed",
  "language_code": "en",
  "language_name": "English",
  "format": "srt",
  "content": "<字幕内容>",
  "available_languages": ["en", "ja"]
}
```

### 注意事项:
- 任务失败时返回错误
- 建议轮询间隔 2-5 秒（本接口有 RPS 限制，请勿高频轮询）
- job_id 仅创建它的账号可查询，他人查询返回 403

### 价格:
- 免费（$0 USD / 请求）

# [English]
### Purpose:
- Get the result of an asynchronous caption job
- For large videos, `/get_video_captions` returns `status="processing"` with a
  `job_id`; use that `job_id` here to retrieve the final captions
- Single-shot, non-blocking query; poll it until the job completes

### Parameters:
- job_id: Async job ID (returned by `/get_video_captions`)
- format: Caption format (applies only when the job is completed)
  - srt: SubRip subtitle format (with timestamps)
  - xml: XML format
  - json3: JSON format
  - txt: Plain text (no timestamps)

### Returns:
#### Processing:
```json
{ "job_id": "123e4567-e89b-12d3-a456-426614174000", "status": "queued" }
```
- status is `queued` or `active`; retry later

#### Completed:
```json
{
  "job_id": "123e4567-e89b-12d3-a456-426614174000",
  "status": "completed",
  "language_code": "en",
  "language_name": "English",
  "format": "srt",
  "content": "<caption content>",
  "available_languages": ["en", "ja"]
}
```

### Notes:
- Returns an error if the job failed
- Recommended polling interval: 2-5 seconds (this endpoint is rate-limited,
  please do not poll aggressively)
- A job_id may only be queried by the account that created it; others get 403

### Price:
- Free ($0 USD / request)
