How this service works
Render common Markdown (headings, bold/italic, links, inline code, fenced code, blockquotes, ordered/unordered lists) to sanitized HTML. No external library.
Output
Returns sanitized HTML markup corresponding to the input Markdown, with proper tags for headings (h1–h6), bold/italic emphasis, anchor tags for links, code and pre elements for inline and fenced code, blockquote elements, and ordered/unordered list structures. Output is sanitized to prevent XSS.
Example use cases
Blog post rendering pipeline
“I have a markdown blog post and need it converted to clean, sanitized HTML so I can inject it into my CMS — here's the markdown: '## My First Post\n\nWelcome to my blog! Here is a **list** of topics:\n- Topic 1\n- Topic 2\n- Topic 3'”
README display in web app
“Take this README markdown and turn it into sanitized HTML I can embed on a project page: '# Project Name\n\nInstall with `npm install mylib`.\n\n```js\nconsole.log("hello");\n```'”
User-submitted comment formatting
“A user submitted a comment in markdown — convert it to safe HTML before I display it: '> Great point!\n\nI agree with **everything** you said. Here's why:\n1. Reason one\n2. Reason two'”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/markdown-to-htmlWhen to prefer
Choose this endpoint when you need a lightweight, dependency-free server-side Markdown-to-HTML conversion without spinning up a full rendering library. Ideal for agents that need to sanitize user-generated Markdown before displaying it on a web page, or for pipelines that produce HTML from Markdown content programmatically. Prefer this over client-side rendering when sanitization and server-side trust are required.
Side effects
- Malformed or empty markdown body returns an error response
- Unsupported or extended Markdown syntax (e.g. tables, footnotes) may not render or may pass through as plain text
- Very large markdown payloads may be rejected or time out
- Network connectivity issues returning HTTP 5xx errors
