Bulk WHOIS Domain Lookup: Age, Expiry, Registrar, DNS & SSL

What does Bulk WHOIS Domain Lookup do?

Bulk WHOIS Domain Lookup checks any list of domains and returns one flat row per domain: registrar, creation date, domain age, expiry date, days until expiry, whether the domain is registered or available, nameservers, DNSSEC, IP addresses, MX records and email provider, SPF and DMARC, plus the SSL certificate issuer and expiry.

Paste domains, website URLs or a Google Sheets link, and download the result as Excel, CSV or JSON. It uses the official RDAP registries, with an automatic classic WHOIS fallback for ccTLDs such as .io, .co, .de, .it, .jp, .me, .mx, .se and .eu. No API key, no rate limits to manage, and you pay only for domains that return data.

It runs on the Apify platform, so you also get an API, scheduling (e.g. a weekly expiry check), integrations (Google Sheets, Make, Zapier, n8n, Slack) and access for AI agents through the Apify MCP server.

Why use it?

• 📅 Domain expiry monitoring: schedule it weekly for your own or your clients' domains and get an alerts entry when a domain or SSL certificate expires within 30 days.
• 🧮 Domain age checks: sort leads, backlinks or marketplaces by domainAgeYears. Old domains are a trust signal, and brand-new ones are a common fraud signal.
• 🛒 Domain investing and availability: registered: false shows domains the registry reports as not registered.
• 📧 Email setup at a glance: emailProvider (Google Workspace, Microsoft 365, Zoho…) and dmarcPolicy for every domain, which is useful for sales prospecting and deliverability audits.
• 🔎 Due diligence: registrar, creation date and nameservers for any list of domains in one table.

How much does a bulk WHOIS lookup cost?

Event	Price
Run start (per GB of memory, default 512 MB)	$0.001
Domain looked up	$0.002 (about $2 per 1,000 domains)

Domains that return no data at all are not billed (a domain that is not registered counts as a result: registered: false). Set Max cost per run and the Actor stops cleanly at that limit.

Use it with AI agents (MCP)

Add https://mcp.apify.com?tools=fguiraud/bulk-whois-domain-lookup to Claude, Cursor or any MCP client and ask: "When do these 20 domains expire, and which ones are older than 10 years?"

FAQ and limitations

• Why are some fields empty for my country's domain? Some ccTLD registries publish very little data (for example no registrar or no dates). The Actor returns whatever the registry provides.
• Is the owner's name or email included? No. Since GDPR, registries redact personal contact data, and this Actor does not collect it.
• Is registered: false a guarantee that I can buy the domain? No. It reflects the registry's answer at that moment; premium or reserved names may still be unavailable.
• Found a problem or need a feature? Open an issue on the Issues tab. Replies within 48 hours.
