Cloudflare Markdown for Agents

This skill enables fetching web content using Cloudflare's Markdown for Agents protocol, which automatically converts HTML pages to clean, structured Markdown format.

What is Markdown for Agents?

Cloudflare's Markdown for Agents is a content negotiation feature that:

• Automatically converts HTML to Markdown at the edge
• Reduces token usage by ~80% compared to raw HTML
• Returns clean, structured content perfect for AI processing
• Adds x-markdown-tokens header showing estimated token count
• Includes Content-Signal headers for AI usage permissions

Usage

Basic Fetch

Use the provided script to fetch any URL with Markdown for Agents support:

scripts/fetch-markdown.sh <URL>

Example:

scripts/fetch-markdown.sh "https://developers.cloudflare.com/agents/"

In Code

TypeScript/JavaScript example:

const response = await fetch("https://example.com/page", {
  headers: {
    Accept: "text/markdown, text/html",
  },
});

const tokenCount = response.headers.get("x-markdown-tokens");
const markdown = await response.text();

cURL example:

curl https://example.com/page -H "Accept: text/markdown"
