Free URL to Markdown API
Put a URL after https://tools.yukai.uk/md/ and get the page as clean Markdown with a short YAML header: title, final URL, status and a token estimate. PDFs work too. Built for AI agents that can only fetch URLs: no sign-up, no key.
Use it from code or an AI agent
curl https://tools.yukai.uk/md/https://example.com/import requests
r = requests.get("https://tools.yukai.uk/md/https://example.com/", timeout=60)
print(r.text) # Markdown with a YAML headerconst r = await fetch("https://tools.yukai.uk/md/https://example.com/", { headers: { accept: "application/json" } });
const { title, content, tokensEstimate } = await r.json();Send Accept: application/json for JSON instead of Markdown. The address after /md/ may keep its own query string; ?url= works too.
Limits
- Plain HTTP fetch: no JavaScript rendering. Pages that build their text in the browser come back almost empty, with a note saying so.
- Up to 100,000 characters per page (the header says when the text was truncated).
- About 10 requests per minute per IP; results are cached for a few minutes.
- Sites that refuse automated requests return an error with a hint, never a fake page.
