## 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`):

```

## When to prefer this

Choose this endpoint when you need a deterministic, template-driven escaped HTML conversion of a user guide written in Markdown or plain text — especially when you want predictable, safe HTML output without AI-generated prose. It is ideal for embedding help documentation into web portals, email templates, or CMS systems where HTML injection risks must be eliminated. Prefer this over generative text endpoints when you already have the content written and just need reliable formatting conversion.
