Domain Intelligence — Bulk DNS, WHOIS & SSL Lookup

Turn a list of domains into clean, structured intelligence in one run. For every domain you get one JSON row with live DNS records, WHOIS registration, and SSL certificate details. No login, no cookies, no proxy setup — paste domains, get data.

Great for lead enrichment, security & infrastructure recon, SSL certificate expiry monitoring, and domain portfolio audits.

What you get per domain

Group	Fields
DNS	A, AAAA, MX, NS, TXT, CNAME records
WHOIS	registrar, creation / expiry / updated dates, domain status, name servers
SSL	certificate subject, issuer, valid_from / valid_to, SAN list, serial

Each group can be toggled off to save cost. Lookups use public resolvers (Cloudflare / Google) for consistent, deterministic results.

Use cases

• Lead enrichment — turn a list of company domains into registrar, hosting, and certificate signals for scoring and routing.
• SSL / certificate expiry monitoring — track valid_to across a whole domain portfolio and catch expiring certs before they break production.
• Security & recon — name-server footprint, WHOIS history, and cert issuer for a list of domains, in one structured dataset.
• Domain portfolio & M&A audits — registrar, expiry, and DNS posture across hundreds of domains at once.

Input

{
  "domains": ["example.com", "https://www.github.com"],
  "includeDns": true,
  "includeWhois": true,
  "includeSsl": true
}

Full URLs are accepted and normalized to the registrable host. Leave domains empty to run the built-in sample.

Output (one item per domain)

{
  "domain": "github.com",
  "dns": { "A": ["140.82.112.3"], "NS": ["dns1.p08.nsone.net", "..."], "MX": ["..."], "TXT": ["..."], "AAAA": [], "CNAME": [] },
  "whois": { "registrar": "MarkMonitor Inc.", "created": "2007-10-09T...", "expires": "2026-10-09T...", "status": ["clientTransferProhibited"], "name_servers": ["dns1.p08.nsone.net"] },
  "ssl": { "subject": "github.com", "issuer": "Sectigo Limited", "valid_from": "...", "valid_to": "...", "san": "DNS:github.com, DNS:www.github.com", "serial": "..." },
  "queried_at": "2026-05-31T00:00:00.000Z"
}

Export as JSON, CSV, Excel, or HTML, or pull via the Apify API.

Pricing

Pay per result: $0.01 per domain enriched. No monthly rental, no platform usage fees — you pay only for the domains you process.

How it works (and why it's low-maintenance)

Lookups are protocol-based — DNS resolution, a TLS handshake for the certificate, and WHOIS over port 43 — not HTML scraping. There are no page layouts to break when websites change, so results stay stable over time. Unresolvable record types return an empty array rather than failing the row.

FAQ

Do I need proxies or API keys? No. Paste domains and run.

What's the difference vs a single-domain WHOIS site? This is built for bulk — hundreds or thousands of domains in one run, with DNS + WHOIS + SSL combined into one structured row per domain, exportable and API-accessible.

Can I monitor SSL expiry on a schedule? Yes — schedule the Actor and watch the ssl.valid_to field across your domain list.

Does it handle full URLs? Yes, https://www.example.com/path is normalized to example.com.
