### Examples

#### Extract YouTube Transcript

```json
{
  "source": {
    "sourceType": "youtube",
    "url": "https://www.youtube.com/watch?v=VIDEO_ID"
  }
}
```

YouTube and TikTok transcript extraction reads **English captions only**. A non-English video, or a video with no captions, returns a `failed` status. For those videos, pass the transcript or a summary using `sourceType: "text"` instead.

#### Extract Article with Custom Instructions

```json
{
  "source": {
    "sourceType": "article",
    "url": "https://example.com/article"
  },
  "customInstructions": "Summarize in 5 bullet points"
}
```

#### AI Research Query

```json
{
  "source": {
    "sourceType": "perplexity-query",
    "text": "latest AI trends in social media marketing"
  }
}
```

#### Transform Raw Text

```json
{
  "source": {
    "sourceType": "text",
    "text": "Your raw content here..."
  },
  "customInstructions": "Rewrite as a Twitter thread"
}
```

### Response

```json
{
  "id": "123e4567-e89b-12d3-a456-426614174000"

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.contouron.com/api/source.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
