Check whether a URL is reachable and what response code it returns.
URL reachability checker. Fetches the target URL and reports HTTP status code, redirect chain, and response time. Uses a server-side proxy to avoid CORS limitations.
HEAD (falling back to GET) request via a Cloudflare Worker proxy to resolve CORS and mixed-content restrictions. Reports final URL after redirect chain (302/301/307/308 followed), HTTP status, Content-Type, server header, and round-trip latency. Timeout: 10s. Private/RFC1918 addresses blocked at the proxy.
Heuristic analysis only — no live URL scanning or external lookups are performed. No data is sent to Teletraan. Results identify structural risk signals in the URL and are not a substitute for a dedicated threat intelligence service.
