Call it from code

How it works

Full GFM: tables, task lists, strikethrough, fenced code, footnotes.

Output is a single self-contained file — the stylesheet is inlined, nothing is fetched from a CDN — so it renders identically offline, inside an email client, or as the input to html-to-pdf.

sanitize (on by default) strips <script>, on* handlers and javascript: URLs, which matters when the Markdown came from a model or an untrusted user.

Parameters

Parameter	Type	Default	Description
markdown *	string	—	Markdown source.
theme	`clean` \| `github` \| `print` \| `minimal` \| `none`	`"clean"`	Built-in stylesheet.
title	string	—	Document `<title>`. Defaults to the first heading.
fullDocument	boolean	`true`	Emit a complete `<html>` document. Off returns just the body fragment.
sanitize	boolean	`true`	Remove scripts, event handlers and `javascript:` URLs.
toc	boolean	`false`	Prepend a table of contents built from the headings.

Response

HTML document. Request JSON output to get it as a string field.

Pairs well with

Markdown → PDF

One call from model-generated Markdown to a shareable PDF.

Strip the chrome, keep the article. Typically 80–90% fewer tokens than raw HTML.
