Markdown API

healthy 3,668 Subscribers

A fast, fully-local Markdown toolkit: render GitHub-flavored Markdown to HTML that is sanitized by default (scripts, style/iframe tags, inline event handlers and javascript: URLs are stripped), strip Markdown down to clean plain text, and extract a heading table of contents with levels, text and URL slugs. Every endpoint accepts input via the query string or the request body (up to 1 MB). Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for CMS and documentation tools, comment systems, static-site pipelines and content rendering.

HTML API

A fast, fully-local HTML toolkit: extract structured data from supplied HTML (title, meta description, canonical link, language, Open Graph and Twitter card tags, links, images, headings and word counts), convert HTML to readable plain text, list all links resolved against a base URL, and sanitize HTML with a strict allowlist (scripts, iframes, inline event handlers, javascript: URLs and unknown tags are stripped). It works on the HTML you send and never fetches URLs (for live link previews see the oanor URL Tools API). Input via the query string or the request body, up to 2 MB. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for scrapers and data pipelines, comment and email sanitization, RAG and content extraction, and CMS tooling.
