## 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 scopeapi-facebook-post-comments-30445083
```

Example prompt: Can you pull all the comments from this Facebook post — post ID 1234567890 — so I can see what people are saying about it?

## When to prefer this

Use this endpoint when you need to retrieve comments from a specific Facebook post by ID and want a simple pay-per-call model with USDC micropayments via x402, without needing a Facebook API account or OAuth setup.

## Known failure modes

- Invalid or non-existent postId returns empty data or error
- Private or restricted post returns no comments due to access limitations
- Rate limiting or payment failure returns 402 Payment Required
- Malformed postId path parameter causes request failure
- Post has been deleted or is no longer accessible
