## 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 sitecheck-shop-social-facebook-post-comments-scraper-07d19615
```

Example prompt: Can you pull the top comments from this Facebook post — https://www.facebook.com/nike/posts/1234567890 — and show me who's commenting, what they're saying, and how many reactions and shares the post has?

## When to prefer this

Use this endpoint when you need to extract comment-level data from a specific public Facebook post without authenticating — ideal for social listening, sentiment analysis, competitor monitoring, or community research. Prefer this over manual inspection or Facebook Graph API when you don't have app credentials or when you need a quick logged-out public view. Not suitable for private posts, paginated deep comment threads, or real-time streaming.

## Known failure modes

- Post is private or requires login — returns empty or error since only logged-out public view is fetched
- Invalid or malformed Facebook URL — returns an error indicating unsupported URL format
- Facebook rate-limiting or blocking the residential proxy — may return partial data or error
- Post has no comments — returns post metadata but empty comments array
- Facebook changes its public DOM/API response structure — scraper may break or return incomplete fields
