## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability youtube-transcript-channel-video-scraper-38cfb74e -d '<json body>'
```

Example prompt: Can you grab the full transcript of this YouTube video https://www.youtube.com/watch?v=dQw4w9WgXcQ in English, and include a single joined text string alongside the timed segments?

## When to prefer this

Choose this endpoint when you need to extract spoken content or captions from YouTube videos at scale, either from specific video URLs or from an entire channel's library with date filtering. It is especially useful for research, content analysis, keyword monitoring, or building searchable archives of video content. Prefer this over general web scrapers when the target is specifically YouTube transcript/caption data.

## Known failure modes

- Video has no captions or auto-generated captions are disabled — no transcript returned
- Private or age-restricted video — access denied
- Invalid or malformed YouTube URL or channel URL
- Language code not available — falls back to another language or returns empty
- Channel has no videos in the specified date range
- maxItems or max_videos limits result in partial data
- API returns empty result set (not charged)

## How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.

## Output

Returns a JSON object with a count of results and an array of items, each containing the video URL, title, video ID, channel ID, channel name, description, channel username, channel thumbnail, and transcript content (as timed segments and optionally as a joined text string).
