## 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 ragradar-grid-facebook-post-comments-fetcher-d7271946
```

Example prompt: Can you pull all the comments from Facebook post ID 1234567890123456 so I can see what people are saying about it?

## When to prefer this

Use this endpoint when you need to programmatically retrieve comments from a specific Facebook post and are willing to pay $0.50 USDC per call. Prefer this over manual scraping or Facebook's official Graph API when you need a pay-per-use model with no subscription, or when you need to access posts that might be difficult to retrieve through official channels.

## Known failure modes

- Invalid or non-existent postId returns empty data or error
- Private or restricted Facebook post may return no comments
- Payment failure via x402/USDC results in 402 response and no data
- Rate limiting or scraping blocks may cause intermittent failures
- Malformed postId path parameter returns 400 or empty response
