Discover subdomains for a domain via Certificate Transparency logs (crt.sh); returns a de-duplicated, sorted list.

Reverse-DNS lookup for an IP: PTR record plus a best-effort list of other domains hosted on the same IP.

Extract all links from a page split into internal and external, each with anchor text and rel attribute, plus per-group counts.

Extract structured elements: heading hierarchy (h1-h6), lists, tables as 2D arrays, and images with alt text, plus element counts.

DNSSEC health check: reports whether a domain is DNSSEC-signed (DNSKEY), has a DS record at the parent, and whether the resolver authenticated the answer, with advisory warnings.

RDAP domain registration lookup: structured registrar, creation/updated/expiry dates, status, nameservers and a computed domain age. A parsed, snake_case JSON alternative to raw WHOIS text.

Fast real-time news scan across 44+ curated domains (configs/search_domain_profiles.json), every item source-attributed.
