## 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-comments-scraper-dbac60a2 -d '<json body>'
```

Example prompt: Scrape the top 50 comments (sorted by top) from this YouTube video — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and include up to 3 replies per comment with their likes, author names, and publish times.

## When to prefer this

Choose this endpoint when you need YouTube comment data without consuming YouTube Data API quota or managing API credentials. It is particularly valuable for competitive research, sentiment analysis, audience feedback collection, or NLP pipelines where raw comment text plus metadata (likes, author, timestamp, pinned/hearted) is needed at low cost per comment. Prefer it over official API wrappers when quota limits are a concern or when comment reply threads are needed with minimal setup.

## Known failure modes

- Video URL or ID is invalid or the video is unavailable — lookup fails without charge
- Video has comments disabled — returns empty results
- maxCommentsPerVideo or maxRepliesPerComment exceeds schema limits (100 and 5 respectively) — request rejected
- Network or scraping timeout on heavily loaded videos — partial or empty results
- Private or age-restricted videos may not return comments
