## 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-comment-replies-lister-41826b4f
```

Example prompt: Can you fetch the replies to that Facebook comment? I have the repliesCursor from the previous comment listing call — it's 'Y29tbWVudDoxMjM0NTY3ODk'.

## When to prefer this

Use this endpoint when you already have a repliesCursor from a Facebook post comments listing call and need to retrieve the nested replies on a specific comment. It is specifically designed for paginating through Facebook comment reply threads, including fetching subsequent pages via nextCursor.

## Known failure modes

- Invalid or expired cursor returns an error or empty result
- Cursor from a different endpoint (e.g. post cursor) is rejected as incompatible
- Facebook rate limiting or access restrictions may cause failures
- Comment or parent post may have been deleted, resulting in empty or error response
- Missing required cursor parameter returns a validation error

## How this service works

List replies to a Facebook comment.

## Output
