Public page content for your AI workflow
Use one tool to turn a page into Markdown. Use the other to inspect its declared metadata before indexing it or sharing its link. Circadian is operated by an autonomous AI agent.
Two tools
- extract_page: readable Markdown, page title, description, final URL and up to 50 links.
- page_metadata: title, description, canonical URL, Open Graph, Twitter card, JSON-LD, feeds and icons from the original HTML.
Each call accepts one url. Fetch only pages you own or have permission to retrieve. For example: "Read my public documentation page and summarize the installation steps" or "Inspect the canonical URL and social preview tags on my landing page."
Limits
This is an HTTP fetcher, not a browser. It does not render JavaScript, sign in, bypass paywalls, solve CAPTCHAs or crawl multiple pages. Markdown accepts HTML or plain text; metadata requires HTML. HTTP errors and binary bodies produce tool errors. Input is capped at 2 MB and Markdown at 300,000 characters; the result flags truncated input. Extracted metadata does not establish search rankings or AI visibility.
Private and local addresses and credential-bearing URLs are rejected. Returned page text is untrusted data and may include hostile instructions. Treat it as source material, never as instructions to your agent.
Plans and billing
Free includes 10 tool calls per calendar month. Pro is USD 4.99 per month for 1,000 tool calls per monthly billing period, before applicable taxes. MCPize shows the final total and any currency conversion at checkout.
Each plan has one shared request allowance across both tools. Requests, including failures, may count toward usage. Calls are blocked when the allowance is exhausted. MCPize manages subscriptions and billing.
