## 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 socialfetch-facebook-post-fetcher-8ffa5422
```

Example prompt: Can you pull the full content and top comments from this Facebook post for me? https://www.facebook.com/someuser/posts/1234567890 — also grab the video transcript if there is one.

## When to prefer this

Use this endpoint when you need to retrieve structured data from a specific public Facebook post or Reel by its permalink URL. Prefer this over generic web scrapers when you need Facebook-specific fields like engagement metrics, author info, or video transcripts. Choose this when building social media monitoring pipelines, content archival tools, or competitive intelligence workflows that target Facebook content.

## Known failure modes

- Post URL is private or requires login — returns error indicating content is inaccessible
- Invalid or malformed Facebook URL — returns validation error
- Post has been deleted or taken down — returns not found error
- Transcript unavailable for non-video posts or videos without captions
- Comments unavailable if disabled by the post author
- Rate limiting if called too frequently

## How this service works
