## 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-fetcher-de72ed33
```

Example prompt: Can you pull all the comments from the Facebook post with ID 1234567890abcdef 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 its ID and are willing to pay $0.50 USDC per call via x402 micropayment. Prefer this over scraping Facebook directly when you need a clean REST API interface without managing Facebook API credentials. Best suited for social listening, sentiment analysis, brand monitoring, or competitive intelligence use cases on Facebook content.

## Known failure modes

- Invalid or non-existent postId returns empty data or error response
- Private or restricted Facebook post returns no data due to access limitations
- Payment failure (insufficient USDC balance) results in 402 response and no data returned
- Rate limiting or upstream Facebook data source unavailability causes request failure
- Malformed postId path parameter returns a 400-level error
