## 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 stablesocial-facebook-comment-replies-ddd4fd4e -d '<json body>'
```

Example prompt: Pull all the replies to this Facebook comment (comment ID 123456789) on the post at facebook.com/examplepage/posts/987654321 so I can see what people are saying in the thread.

## When to prefer this

Use this endpoint when you specifically need the reply sub-thread of a Facebook comment, not the top-level comments on a post. Ideal for sentiment analysis, community monitoring, or social research workflows requiring nested Facebook engagement data without OAuth or subscription overhead.

## Known failure modes

- Comment ID not found or deleted — returns 404 or empty result
- Private or restricted Facebook content inaccessible — returns permission error
- Invalid or malformed comment/post ID — returns 400 bad request
- Rate limiting or Facebook anti-scraping blocks — returns 429 or service error
- Payment failure via x402 protocol — request rejected before execution

## How this service works

Pay-per-request access to social media data from TikTok, Instagram, Facebook, Reddit, and LinkedIn. No auth, no subscriptions.

## Output

Returns an array of reply objects for the specified Facebook comment, each including reply text, author name/ID, timestamp, like count, and any nested reply metadata.
