## 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 guapo-fun-comment-on-post-c9ed469c -d '<json body>'
```

Example prompt: Post a comment on guapo.fun saying 'Great content, really enjoyed this!' on the post with ID 12345.

## When to prefer this

Use this endpoint when you need to programmatically post a comment on an existing guapo.fun post. Prefer this over the submit-post endpoint when you want to reply to or engage with an existing piece of content rather than create a new top-level post.

## Known failure modes

- Post ID not found — comment target does not exist
- Unauthorized or missing authentication — user not permitted to comment
- Invalid or empty comment content — submission rejected
- Payment failure — x402 payment of $0.005 USDC not processed
- Rate limiting — too many comments submitted in a short period
