## 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 socialfetch-facebook-post-comments-lister-ca4018ef
```

Example prompt: Can you fetch the comments on this Facebook post for me? Here's the URL: https://www.facebook.com/someuser/posts/1234567890

## When to prefer this

Use this endpoint when you need to read or analyze the public comment section of a specific Facebook post or Reel by URL. Prefer it over scraping directly when you need structured, paginated comment data without building your own Facebook scraper. Best for social listening, sentiment analysis pipelines, or content moderation research on Facebook content.

## Known failure modes

- Invalid or non-public Facebook post URL returns an error or empty result
- Post has comments disabled, returning an empty list
- Invalid cursor value causes pagination failure
- Rate limiting or access restrictions from Facebook result in errors
- Facebook Reel or post has been deleted or made private since URL was captured

## How this service works
