How this service works
Convert Markdown to HTML. Send JSON {markdown: string}. Returns html, headings [{level,text}], chars_in. Supports headings, paragraphs, bold/italic/strike, inline and fenced code, lists, task lists, blockquotes, hr, GFM tables with alignment, and links/images (http/https/mailto only). Raw HTML is escaped, not passed through. Not a full CommonMark implementation. Max body 512 KB. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.
Output
Returns a JSON object with: 'html' (the rendered HTML string), 'headings' (an array of objects each with 'level' integer and 'text' string), and 'chars_in' (integer count of input characters). Raw HTML in the input is escaped rather than passed through, ensuring safe output.
Example use cases
Blog post markdown rendering
“I have a markdown blog post and need it converted to HTML so I can embed it in a web page — here's the content: '## My Journey\n\nI started learning **Rust** in 2023...\n\n- Fast\n- Safe\n- Fun'”
README to HTML for documentation site
“Take this README.md content and convert it to HTML for me, including the GFM table and task list sections, so I can display it on our docs page.”
Extract heading outline from markdown
“I've got a long markdown document and want to pull out all the headings as a structured outline — can you convert it to HTML and give me the headings list with their levels?”
Technical details
Endpoint
POSThttps://api.jagent.dev/v1/markdown-to-html?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, safe, server-side Markdown-to-HTML conversion that also returns a structured headings outline. It is particularly well-suited for agentic workflows that need to sanitize user-supplied markdown (raw HTML is escaped), extract document structure (headings with levels), or render GFM features like tables, task lists, and fenced code blocks. Not a full CommonMark implementation, so avoid for edge-case CommonMark compliance needs.

- Request body exceeds 512 KB limit — request rejected
- Missing 'markdown' field in JSON body — validation error
- Non-string value for markdown field — type error
