URL inspector

Quick URL health and metadata check — parse the URL structure, verify reachability, and pull page metadata in one pass.

When to use this pack

An agent needs to verify a URL is live and understand what's behind it before recommending it, embedding it, or crawling it. Combines structural parsing (protocol, host, path), liveness check (status, latency, redirects), and metadata extraction (title, description, OG tags).

Tools in this pack

• URL parse $0.001 POST /api/url-parse Parse a URL into components: protocol, host, port, path, query params (decoded), hash, origin, punycode hostname.
• HTTP check $0.003 POST /api/http-check Check any public URL: status code, latency, final URL after redirects, and response headers. The uptime primitive for agent monitors.
• Page metadata $0.002 undefined Fetch page metadata for a URL: title, description, OpenGraph, Twitter cards, canonical URL, favicon.

Workflow

1. Call url-parse to decompose the URL into protocol, hostname, path, query parameters, and fragment.
2. Call http-check to verify the URL is reachable — status code, latency, redirect chain.
3. Call meta to pull the page's title, description, canonical URL, and OpenGraph/Twitter card tags.
