## 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 arch-linux-package-info-lookup-a8cc38c3 -d '<json body>'
```

Example prompt: Can you look up the official Arch Linux repository info for the package 'ffmpeg' and tell me the version and description?
