🧠 Domain WHOIS Lookup — Bulk Registrar, Expiry, Name Server & Status Codes

Bulk WHOIS lookup actor. Pull registrar name, creation date, expiration date, last-updated date, name servers, registrant organization (where public), and EPP status codes for any list of domains. Built as a drop-in alternative to DomainTools, WhoisXML API, who.is, and the redacted port-43 WHOIS pipes that broke after GDPR + the ICANN RDAP migration.

Why Domain WHOIS Lookup Beats DomainTools, WhoisXML API, who.is & MarkMonitor

Feature	NexGenData Domain WHOIS Lookup	DomainTools	WhoisXML API	who.is (free)	MarkMonitor
Cost	$0.002 per domain, pay-per-event	$99+ / month base	$19+ / month (500 lookups)	Free (rate-limited, CAPTCHA)	Enterprise contract
Bulk input	Thousands per run	Plan-gated	Plan-gated	One domain per page	Sales-call required
RDAP + WHOIS fallback	Both, transparent	RDAP	RDAP	Legacy only	Both
GDPR-redacted fields	Returned as null (explicit)	Returned as null	Returned as null	Inconsistent	Returned as null
Output	JSON / CSV / Excel	JSON / proprietary	JSON	HTML page	PDF report
API auth	Apify token	Account + plan	API key + plan	None	Account manager
Monthly minimum	None	$99+	$19+	None	$$$$
Drop-in for whois CLI	Yes, JSON-normalized	No	No	No	No

Most teams pick this actor because it is cheaper than DomainTools' enterprise WHOIS tier, has no monthly minimum like WhoisXML, and bypasses the CAPTCHA + rate limit on free WHOIS sites. It is a true drop-in alternative to DomainTools, WhoisXML, and who.is for cybersecurity, brand protection, and domain investment teams.

What You Get

Every record contains:

• domain — normalized domain looked up
• registrar_name — registrar display name
• registrar_iana_id — IANA numeric ID (where exposed by RDAP)
• created_date — registration / creation date (ISO-8601)
• updated_date — last changed date
• expires_date — expiration date
• status — array of EPP status codes (clientTransferProhibited, etc.)
• nameservers — authoritative NS hostnames, lowercased
• registrant_country — present when not GDPR-redacted
• registrant_organization — present when not GDPR-redacted
• admin_email — usually a privacy-proxy address
• source — rdap or whois
• lookup_timestamp — when the lookup ran

Output streams to a clean Apify dataset — export CSV, JSON, Excel, RSS, or pull from the dataset API directly.

Use Cases

• Cybersecurity / threat-intel teams — bulk-classify domains in a phishing feed by registrar + creation date
• Brand protection — monitor trademark-infringing typo domains, sorted by registrar and expiry
• Domain investors — track expiry dates across a watchlist of 10k+ domains for backorder targeting
• Compliance officers — quarterly audit of vendor domains for impersonation risk
• SEO agencies — verify client domain expiry + name server changes before launches
• M&A due-diligence — pull WHOIS history snapshots on every domain a target owns

Quick Start (Python)

from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("nexgendata/domain-whois-lookup").call(run_input={
    "domains": ["apple.com", "openai.com", "anthropic.com"]
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["domain"], item["registrar_name"], item["expires_date"])

Pricing — Pay Per Domain

• Actor start: $0.005
• Domain lookup: $0.002

A 1,000-domain batch costs $2.00. No monthly minimum, no API key juggling.

FAQ

Q: Where does the data come from? A: The actor speaks RDAP (RFC 7480-7484) directly against IANA-listed RDAP servers, with a fallback to legacy port-43 WHOIS for the long-tail ccTLDs that haven't migrated. No third-party paid API in the chain.

Q: Why are some fields null? A: Post-GDPR, registrar / registry RDAP responses redact most personal registrant data for .com, .net, .org, and all EU TLDs. We return null rather than fabricating values.

Q: How often does the data refresh? A: WHOIS / RDAP returns whatever the registrar currently has on file — typically refreshed within hours of any change.

Q: Does this work for .cn, .ru, .jp, .de and other ccTLDs? A: Yes — those TLDs are served via the legacy port-43 fallback (RDAP support varies by registry). Output schema is identical.

Q: Is bulk WHOIS legal? A: Yes. WHOIS / RDAP data is published by ICANN-accredited registries / registrars for exactly this purpose. The redactions enforced by GDPR happen at source.

Q: Can I use this in MCP for an AI agent? A: Yes — pair it with domain-intelligence-mcp-server so Claude / ChatGPT can call WHOIS as a tool.

How NexGenData Pricing Works

Every NexGenData actor uses pay-per-event pricing — you only pay for results that actually land in your dataset. No monthly minimum, no seat fees, no surprise overage bills.

• Actor Start: a single-event charge each time you spin the actor up (scaled to memory size)
• Result: charged per item written to the default dataset
• No charge for retries, internal proxy rotation, or failed sub-requests — those are absorbed by the platform
