请求体
JSON，POST 到这个接口。
- urlstring
https://www.youtube.com/watch?v=nS3oOb6VwJq
YouTube 视频或 Short 的 URL（例如 "https://www.youtube.com/watch?v=dQw4w9WgXcQ" 或 "https://www.youtube.com/shorts/Fir1x9cw2vg"）。
- captionKindenum
接受哪种字幕轨道："manual" 只接受创作者编写的字幕，"automatic" 只接受 YouTube 的语音识别，"any" 接受现有的任一种。
- languagestring
首选字幕语言代码（例如 "en"、"es"）。默认为英语。如果视频没有该语言的字幕，你会得到该视频已有的其他语言的转录文本；结果中的 `language` 字段会说明是哪种语言。将 `captionKind` 设为 "manual" 或 "automatic" 时，不会返回其他语言。
- requireFieldsarray
可选；省略时路由不变，由最便宜的数据源处理。列出本次请求必须能返回的输出字段，例如 `views`，请求就只会由能返回全部这些字段的数据源处理。未列出的字段，只要处理请求的数据源有，仍会照常返回。这可能提高你的价格：最便宜的数据源无法返回某个列出的字段时，会改由更贵的数据源处理，并按它的价格报价和扣费。如果某个转录文本确实没有某个列出的字段，该字段仍可能缺失。如果列出的字段组合没有任何单一数据源能同时返回，请求会作为无效输入被拒绝，不扣费。

Present only when `found` is false, and says why there is no result. `not_found`: the source states the target does not exist, or returned nothing for it. A `found: false` answer is a successful call, not an error, and `costUsd` is what it actually cost.
