Domain WHOIS, DNS & SSL Checker: Bulk Expiry, Registrar, MX

Check hundreds of domains in one run: who registered them and when they expire, where their e-mail goes, and whether their SSL certificate is valid — one clean JSON record per domain.

• Registration (RDAP, WHOIS fallback): registered or available, registrar and abuse e-mail, creation, update and expiry dates, days until expiry, status codes, nameservers, DNSSEC. RDAP covers .com, .net, .org, .ua, .uk and 1,000+ other TLDs; WHOIS is used for the rest (.io, .de…).
• DNS: A, AAAA, MX, NS, TXT, CNAME, CAA, SOA, plus parsed SPF and DMARC records.
• SSL certificate: trusted or not (and why), issuer, subject, alternative names, valid from/to, days left, TLS version; falls back to www. when the bare domain has no HTTPS.
• Accepts URLs and internationalised domains; duplicates are checked once.

Use it for expiry and certificate monitoring (schedule it daily), domain portfolio audits, e-mail deliverability checks (MX/SPF/DMARC), lead research and SEO.

Why this Actor

	This Actor	Typical alternatives in the Apify Store (Oct 2026)
One price, three checks	Registration + DNS + SSL for $2 per 1,000 domains	$2.50–3 per 1,000 for WHOIS alone, some plus start fees
Coverage	RDAP for 1,200+ TLDs with WHOIS fallback (.io, .de…)	Often WHOIS only
E-mail setup	MX, SPF and DMARC parsed	Raw TXT records
Expiry monitoring	Days until domain and certificate expiry in one record — schedule it daily	Two separate tools

Input

{
  "domains": ["apify.com", "https://www.github.com/about", "wikipedia.org"],
  "whois": true,

    "SPF": "v=spf1 include:_spf.google.com ~all",
    "DMARC": "v=DMARC1; p=reject"
  },

  }
}

(Values above are illustrative.) An invalid domain gets an error field and is not charged.

Pricing

Event	Price	What counts
domain	$2 per 1,000	one checked domain (registration + DNS + SSL together)

Plus Apify's standard start fee of $0.05 per 1,000 runs. The run stops before it would exceed your maximum charge per run.

Use with AI agents and code

• MCP (Claude, Cursor, VS Code, any MCP client): add https://mcp.apify.com?tools=ai_admin/domain-whois-dns-ssl as an MCP server — the agent gets one tool with this Actor's input schema and pays per use through your Apify account.
• One HTTP call that returns the results:

curl -X POST "https://api.apify.com/v2/acts/ai_admin~domain-whois-dns-ssl/run-sync-get-dataset-items?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"domains": ["apify.com", "github.com"], "whois": true, "dns": true, "ssl": true}'

Limits

• Registries hide personal registrant data (GDPR), so owner names and e-mails are usually not available.
• Some WHOIS servers limit how often they answer; a domain may then come back with a warnings entry instead of registration data. Run large lists in a few smaller batches if that happens.
• DNS is resolved through Cloudflare's public DNS-over-HTTPS resolver.
