## 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 agdata-youtube-comments-api-afba0409 -d '<json body>'
```

Example prompt: Pull the top 50 comments from this YouTube video — https://www.youtube.com/watch?v=dQw4w9WgXcQ — sorted by top, and give them to me as structured data with likes and reply counts.

## When to prefer this

Choose this endpoint when you need structured comment data from a YouTube video quickly and without setting up YouTube API credentials. It is ideal for agents doing sentiment analysis, audience research, or content monitoring on YouTube videos, especially when paying per-call via stablecoins is acceptable and commenter identity is not required.

## Known failure modes

- Invalid or non-existent YouTube video URL returns an error
- Private or age-restricted videos may not return comments
- Limit parameter out of range (below 1 or above 100) is rejected
- Video with comments disabled returns empty or error response
- Network or upstream YouTube blocking causes partial or failed response
