## 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 radar-youtube-comments-scraper-0dacedfb -d '<json body>'
```

Example prompt: Scrape the top 50 comments from these two YouTube videos — https://www.youtube.com/watch?v=jNQXAC9IVRw and https://www.youtube.com/watch?v=dQw4w9WgXcQ — sorted by top, and only keep comments that mention 'price' or 'refund'. Include reply threads, up to 10 replies per comment.

## When to prefer this

Choose this endpoint when you need to programmatically extract YouTube comment data at scale — especially with keyword filtering to control cost (only matching comments are charged), multi-video batch collection, or reply thread traversal. Preferred over manual YouTube Data API integration when you want pay-per-result pricing in USDC with no API key setup, or when you need a simple POST JSON interface for agent-driven workflows.

## Known failure modes

- Invalid or private/deleted YouTube URL returns empty results or an error
- No comments match keyword filter — returns count:0 with empty items array and no charge
- Rate limiting or YouTube access restrictions may reduce or truncate results
- Invalid date format for publishedAfter may cause unexpected filtering behavior
- Exceeding maxComments or maxCommentsPerVideo caps silently truncates results
- Payment failure via x402/USDC halts the request before execution

## How this service works

Fast tools (web read, domain RDAP/DNS/SSL, Federal Register, clinical trials, Polymarket+Kalshi odds, OSV vulnerabilities) and data APIs (leads, jobs, YouTube, Reddit, Trends, tenders...). POST JSON, pay per call in USDC on Base via x402. Charged only when results are returned.

## Output

A JSON object with a count field and an items array; each item represents one comment and includes the comment text, metadata (author, timestamp, like count), a flag indicating whether it is a reply (isReply), and the parentCommentId when applicable. Only comments matching the keyword filter (if provided) are included and charged.
