# Transcrição

Você pode obter transcrições de vídeos do YouTube fornecendo um **ID do vídeo do YouTube** e um `language_code` para o `youtube_transcript` source.

{% hint style="warning" %}
As transcrições são separadas das legendas e das legendas ocultas (CC). Para extrair legendas e legendas ocultas, use o [YouTube Subtitles](/api-targets/pt-br/video-e-midias-sociais/youtube/youtube-subtitles.md) source.
{% endhint %}

## Exemplos de solicitação

Os exemplos a seguir demonstram como recuperar a transcrição em inglês de um vídeo do YouTube, especificamente quando a transcrição foi fornecida pelo uploader.

```
GET https://developers.oxylabs.io/api-targets/pt-br/video-e-midias-sociais/youtube/youtube-transcript.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
