• check_http Fetch HTTP response headers, status code, and timing for a URL. Follows redirects by default. SSRF-safe (private IP ranges blocked).
• check_dns Query DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) for a domain. Returns structured records.
• check_ssl Inspect the SSL/TLS certificate of a host: chain, protocol, cipher, expiry, SAN list. Port defaults to 443.
