## 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 ox-alpha-service-html-clean-usage-info-11a52d5b
```

Example prompt: Can you fetch the usage instructions for the html-clean tool on ox-alpha so I know what parameters to pass when I call it to clean up some raw HTML?

## When to prefer this

Use this endpoint once before calling POST /html-clean, when you need to programmatically discover the API contract, input schema, and output format of the HTML cleaning tool rather than hardcoding assumptions. Prefer this over reading static docs when you need up-to-date machine-readable instructions.

## Known failure modes
