# RagRadar Grid — Facebook Post Comments

> RagRadar Grid — Facebook Post Comments is a paid API for AI agents from grid.ragradar.space, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Fetches comments on a specific Facebook post by post ID, returning social engagement data via micropayment-gated REST API.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-a9854509
```

Example prompt: Pull all the comments from Facebook post ID 1234567890 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. Best suited for social listening, sentiment analysis pipelines, competitive intelligence, or brand monitoring workflows that require structured comment data from public Facebook posts without building a direct Facebook API integration.

## Known failure modes

- Invalid or non-existent postId returns empty data or error response
- Private or restricted Facebook post returns no accessible comment data
- Payment failure (x402 USDC micropayment not processed) blocks the request
- Rate limiting or quota exhaustion on the underlying data source
- Malformed postId path parameter causes a 400 or 404 error

## How this service works
