Markdown to HTML API

Convert Markdown to HTML via REST API. Supports GitHub Flavored Markdown (GFM) including tables, task lists, strikethrough, fenced code blocks, and inline HTML. Returns clean, sanitized HTML ready to render in a browser.

How it works

POST a Markdown string. The API parses it and returns equivalent HTML. Supports standard Markdown headings, bold, italic, links, images, code blocks (with optional language hint), blockquotes, ordered and unordered lists, and horizontal rules.

Use cases

• Render Markdown content in a CMS or blog platform
• Convert README files to HTML for documentation sites
• Process LLM outputs (often in Markdown) for display in web apps
• Generate HTML email bodies from Markdown templates
