How this service works

Convert a web page (by URL) or raw HTML into clean, readable Markdown plus structured metadata (title, description, Open Graph tags, canonical URL, language). Strips scripts, styles and boilerplate tags; preserves headings, links, images, lists, code blocks and tables. Built for agents that need web content as LLM-ready text. POST a JSON body like: {"url":"https://example.com/article"}

Output

Returns clean Markdown text of the page content with scripts, styles, and boilerplate removed, plus structured metadata: title, meta description, Open Graph tags, canonical URL, and detected language.

Example use cases

Example prompt

“Grab the article at https://example.com/article and convert it to clean markdown — I need the full readable content plus the title, description, and any Open Graph tags so I can feed it into my LLM pipeline.”

Technical details

Endpoint

POSThttps://keyronne.com/api/markdown?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI agent needs to ingest web content as LLM-ready text — particularly when you need both cleaned Markdown and structured metadata (OG tags, canonical URL, language) in a single call. Prefer this over generic scraping tools when the goal is readable prose for an LLM rather than raw HTML or structured data extraction.

Side effects

URL is unreachable or returns a non-200 status — API returns an error indicating the fetch failed
HTML exceeds 2 MB limit — request rejected with size-limit error
URL points to a private/internal network address — blocked for security reasons
Malformed JSON body or missing both url and html fields — validation error returned
Page has no meaningful content (e.g. pure JavaScript SPA with empty server-side HTML) — returns sparse or empty markdown

Input
