Domain WHOIS Lookup & Availability Checker (RDAP)

Look up WHOIS data for thousands of domains in one run. Paste domains, URLs or email addresses and get each domain's registrar, creation date, expiry date, domain age, days until expiry, EPP status codes, nameservers, DNSSEC and availability, plus live DNS: IP addresses, MX records, SPF record and the email provider (Google Workspace, Microsoft 365, Zoho...). Works for 1,200+ TLDs: every gTLD through official RDAP, and ccTLDs like .io, .co, .de, .eu, .it, .ch, .jp, .ru, .me, .us through RDAP or the registry's own WHOIS server. $1 per 1,000 domains.

What can this WHOIS lookup tool do?

• 🌍 Official sources only: queries the registry's RDAP server listed by IANA (the modern, structured replacement for WHOIS), and falls back to the registry's port-43 WHOIS server for ccTLDs without RDAP. No third-party WHOIS API, no API key.
• 📅 Dates that matter: createdAt, updatedAt, expiresAt, plus computed domainAgeDays and daysUntilExpiry for sorting and alerts.
• ✅ Domain availability checker: available: true when the registry has no record for the domain.
• 🏷️ Registrar and status: registrar name and IANA ID, normalized EPP status codes (client transfer prohibited, redemption period...), DNSSEC.
• 📧 Live DNS and email provider: A records, MX, NS, SPF and the detected email provider, which helps with lead qualification and deliverability checks. Switch it off for pure WHOIS.
• ⚡ Fast and cheap: plain HTTPS and WHOIS, no browser. About 400 domains in under a minute, with polite per-registry limits so you don't get rate-limited.
• 🔒 Privacy-friendly: returns domain-level data only. Registrant names, emails, phone numbers and addresses are never collected.
• 🤖 Simple JSON input for the API, Zapier, Make, n8n and the Apify MCP server (AI agents).

Who uses bulk WHOIS lookup?

• Domain investors: check availability, age and expiry dates of thousands of names, and catch domains about to expire.
• Brand protection & security teams: find newly registered look-alike domains (domainAgeDays < 30), check registrars and nameservers.
• Sales & lead generation: qualify companies by domain age and email provider (Google Workspace vs Microsoft 365).
• Fraud, KYB and merchant risk: a domain registered last week is a classic risk signal.
• IT & agencies: monitor expiry dates of every domain you manage. Schedule a daily run and alert on daysUntilExpiry < 30.

How to use it

1. Paste domains (or URLs or email addresses), one per line. Subdomains are reduced to the registrable domain (blog.example.co.uk -> example.co.uk).
2. Keep live DNS on (default) or switch it off for pure WHOIS data.
3. Click Start, or call it from the API and schedule it.

Input example

{
  "domains": ["shopify.com", "notion.so", "spiegel.de", "my-brand-new-startup-name-2026.com"],
  "includeDns": true
}

Empty input runs a small demo.

Pricing

Pay per result, no subscription:

Event	Price
Actor start	$0.001 per run (per GB of memory, default 256 MB = 1 event)
Domain looked up	$0.001 ($1 per 1,000 domains)

Domains that fail (for example a registry that blocks public WHOIS) are returned with an error and are never charged. Set a maximum cost per run in the run options and the Actor stops cleanly when it is reached.

WHOIS Actor	Price per 1,000 domains
This Actor	$1
Typical WHOIS lookup Actors on the Store	$2.50 - $3 + start fees
Paid WHOIS APIs	$10 - $50

Coverage notes

• Data comes straight from each registry, so fields vary by TLD. Some ccTLD registries publish less: .de shows status and nameservers but no dates, .com.au has no creation date, and .es, .gr, .vn and a few others don't offer public WHOIS at all (returned as free errors).
• available: true means the registry has no record. Premium or reserved names may still be unavailable to register; confirm at your registrar.
• Registrant contact details are not returned (most are redacted under GDPR anyway).

FAQ

Is WHOIS lookup legal? Yes. WHOIS and RDAP are public services that registries run so anyone can look up domain registration data. This Actor reads only domain-level fields and respects per-registry rate limits.

WHOIS vs RDAP? RDAP is the official JSON successor to WHOIS, and ICANN requires it for all gTLDs. This Actor uses RDAP wherever the registry supports it and classic WHOIS elsewhere, and returns one consistent format.

Can I monitor domain expiry? Yes. Schedule the Actor daily or weekly with your domain list, and filter on daysUntilExpiry in a webhook, Zapier, Make or Google Sheets.

Can I use it from code?

import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: 'YOUR_TOKEN' });
const run = await client.actor('best_apis/domain-whois-lookup').call({ domains: ['example.com', 'apify.com'] });
const { items } = await client.dataset(run.defaultDatasetId).listItems();
