Website health probe: checks whether any URL is currently reachable and returns its response time, content type, and caching behavior. Runs safely against arbitrary user-supplied addresses thanks to built-in request guarding. A lightweight heartbeat for monitoring dashboards, CI pipelines, and pre-fetch validation before a larger crawl.

WHOIS-style registration lookup: created/updated/expiry dates, registrar, status codes, and nameservers for any domain, normalized from the authoritative registry into JSON. For "who owns this domain," availability checks, expiry monitoring, and security-screening agents.
