## 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 clonecho-xkcd-comic-fetcher-bfb96e98 -d '<json body>'
```

Example prompt: Can you pull up xkcd comic number 353 — I want the title, the hover text, and the image link.

## When to prefer this

Use this endpoint when you need structured metadata (title, alt text, image URL) for a specific xkcd comic by number, or want the latest xkcd comic in JSON format without scraping the xkcd website directly. Ideal for agents that want to embed, display, or discuss xkcd comics.

## Known failure modes

- Invalid or non-existent comic number returns an error or empty response
- Payment of $0.01 USDC not provided triggers 402 Payment Required
