Markdown For Agents Checker
Check if any website supports Cloudflare's Markdown for Agents content negotiation standard. Test HTTP text/markdown response headers, token savings, and AI content compatibility.
What is Markdown for Agents?
The web was originally designed for human visual rendering, sending heavy HTML structures, scripts, and styling to web browsers. However, AI agents, LLMs, and RAG pipelines require concise, clean, structured data without raw HTML clutter. Cloudflare introduced Markdown for Agents, an open HTTP content negotiation standard that enables servers to return native text/markdown when an incoming HTTP request includes the Accept: text/markdown header.
Read our in-depth guide on Markdown for Agents: What It Is, How It Works, and Key Benefits.
Why Test Website Accept: text/markdown Support?
Serving Markdown directly from the edge provides massive advantages for AI-driven applications and web scraping:
- Up to 80% Token Reduction: HTML pages often contain tens of thousands of tokens of boilerplate code. Pure Markdown strips away HTML elements while retaining headings, lists, tables, and links.
- Sub-second Response Times: Edge servers return Markdown directly without executing client-side JavaScript or complex headless browser rendering.
- Better Context Window Utilization: AI models like GPT-4, Claude, and Gemini can process up to 5x more actual content within their prompt context windows.
- Reduced Server and API Costs: Minimizes payload bandwidth and token costs for LLM inference.
How the Markdown for Agents Checker Works
Our free online Markdown for Agents Checker tests any public URL by inspecting HTTP content negotiation behavior.
- HTTP Request Dispatch: Sends an HTTP request to the target URL with the
Accept: text/markdownheader. - Header & Content-Type Analysis: Verifies if the web server responds with
Content-Type: text/markdownor defaults totext/html. - Token Efficiency Calculation: Estimates total LLM tokens for raw HTML versus clean Markdown and calculates token savings percentage.
- Extracted Content Preview: Renders the returned Markdown or extracted document text for instant inspection and download.

Frequently Asked Questions
What is the Accept: text/markdown HTTP header?
It is an HTTP content negotiation header sent by AI crawlers and HTTP clients to request a Markdown representation of a webpage instead of raw HTML.
Which platforms support native Markdown for Agents?
Sites hosted on Cloudflare (with Markdown for Agents enabled), modern static site generators, and headless CMS platforms supporting content negotiation can serve native Markdown.
How does Markdown save LLM tokens?
Raw HTML contains tags, CSS classes, script blocks, and inline styles that consume thousands of tokens. Markdown preserves structural text (headers, lists, tables) using minimal characters, reducing token count by up to 80%.
What if a website does not support text/markdown natively?
If the server returns HTML, our checker flags that conversion is required. AI pipelines can convert the HTML payload to Markdown using parser tools or workers.
Is this tool free to use?
Yes, this tool is completely free with no registration or API keys required.
