## 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 x402vid-youtube-comment-analyzer-a485f831 -d '<json body>'
```

Example prompt: Can you analyze the comments on this YouTube video — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and give me a report on what viewers are saying? Sample up to 80 comments.

## When to prefer this

Choose this endpoint when you need structured AI intelligence specifically about a YouTube video's comment section — audience sentiment, recurring themes, viewer reactions — rather than the video content itself. It is pay-per-call with no subscription overhead, making it ideal for on-demand, agent-driven workflows. Prefer this over generic scraping tools when you want an AI-synthesized report rather than raw comment data.

## Known failure modes

- Invalid or private YouTube URL returns an error — video must be publicly accessible
- Comment section disabled or empty results in no data to analyze
- max_comments exceeding 100 is clamped or rejected
- Payment failure (insufficient USDC balance or x402 auth error) blocks the call
- Rate limiting if too many calls are made in quick succession
