    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Registration intelligence for a domain via RDAP (the modern WHOIS). Returns registrar, creation/expiration/last-changed dates, domain age in years, EPP status codes, nameservers, DNSSEC state, and abuse contact. Use to vet a company, assess a lead, or judge how established a domain is.

    Description, as the server wrote it

    Description, as the server wrote it
    Assess whether a domain (or the domain of an email address) can receive mail and how strong its sender authentication is. Returns MX presence, SPF and DMARC policy, whether it's a free consumer provider (gmail, etc.) or a known disposable/temp-mail provider, and an overall verdict. Use to qualify leads and flag throwaway signups.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Discover a domain's public subdomains (app., api., staging., and so on) from Certificate Transparency logs, querying crt.sh and Cert Spotter in parallel and returning whichever answers first. Useful for mapping a company's public attack surface or infrastructure. If both sources are down the call returns an error rather than an empty list.

    Description, as the server wrote it
    Fingerprint the technology behind a website by fetching its homepage. Detects web server, CMS/framework (WordPress, Shopify, Next.js, etc.), CDN, analytics, and returns the page title, final URL after redirects, and key response headers. Use for competitive research and lead enrichment.

    Description, as the server wrote it
    Look up DNS records for a domain via Cloudflare DNS-over-HTTPS. Returns A, AAAA, MX, NS, TXT, CNAME, and SOA records. Use to see where a domain is hosted, who runs its mail and DNS, and what verification/policy TXT records it publishes.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
