## 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 reddit-post-comments-fetcher-51b34dc2
```

Example prompt: Can you fetch all the comments from this Reddit post with ID t3_abc123 so I can see what the community is saying about it?

## When to prefer this

Use this endpoint when you need to retrieve community discussion, replies, or reactions to a specific Reddit post and have the post ID available. Prefer this over scraping Reddit directly when you need a structured, pay-per-call API approach within an x402 micropayment workflow.

## Known failure modes

- Invalid or non-existent postId returns 404 or empty result
- Post has no comments returns empty array
- Reddit API rate limiting or downstream access issues cause 5xx errors
