## 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 socialfetch-youtube-video-comments-5a1451e4
```

Example prompt: Can you pull the top comments from this YouTube video for me? https://www.youtube.com/watch?v=dQw4w9WgXcQ — sorted by top-ranked.

## When to prefer this

Use this endpoint when you need to programmatically retrieve comments from a YouTube video by URL, especially when you want to sort by top or newest and paginate through large comment threads. Prefer this over manual scraping or YouTube Data API when you want a simple, pay-per-call REST interface without OAuth setup.

## Known failure modes

- Invalid or non-YouTube URL returns an error
- Video has comments disabled returns empty list or error
- Malformed or expired pagination cursor returns an error
- Rate limiting or quota exceeded returns a 429-style error
- Private or deleted video returns an error

## How this service works

List comments on a YouTube video by URL.
