🌐 WHOIS Domain Lookup — Bulk Registration, Owner, Expiry & Name Server Records

Bulk WHOIS lookup for any list of domains. Returns owner, registrar, creation date, expiration date, name servers, and EPP status codes in one JSON schema. Built as a drop-in alternative to DomainTools, WhoisXML API, RapidAPI WHOIS, and who.is for portfolio monitoring, expired-domain hunting, and competitor research.

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

Feature	NexGenData WHOIS Domain Lookup	DomainTools	WhoisXML API	RapidAPI WHOIS	who.is
Cost	$0.002 per domain, pay-per-event	$99+ / month base	$19+ / month (500 lookups)	$10+ / month (500/mo)	Free (rate-limited)
Bulk input	Thousands per run	Plan-gated	Plan-gated	Plan-gated	One per page
RDAP support	Yes (RFC 7480 native)	Yes	Yes	Mixed	No
GDPR-aware nulls	Explicit null fields	Yes	Yes	Inconsistent	Inconsistent
Output formats	JSON, CSV, Excel, RSS	JSON / proprietary	JSON / XML	JSON	HTML page
Schedule + webhooks	Native	Account-level	Account-level	None	None
Monthly minimum	None	$99+	$19+	$10+	None
API auth	Apify token	License + account	API key	RapidAPI key	None
Drop-in for whois CLI	Yes, JSON-normalized	No	Partial	Partial	No

Most teams pick this actor because it is cheaper than WhoisXML's monthly tiers, has no plan cap like RapidAPI's 500-lookup ceiling, and bypasses the CAPTCHA + rate limit on free WHOIS sites. A true drop-in alternative to DomainTools and WhoisXML for domain investors, brand protection teams, and security ops.

What You Get

Each record contains:

• domain — normalized lowercase domain
• registrar_name
• registrar_iana_id — IANA registrar ID (RDAP only)
• created_date — ISO-8601 registration date
• updated_date
• expires_date
• status — array of EPP status codes
• nameservers — lowercased authoritative NS list
• registrant_organization — where not GDPR-redacted
• registrant_country
• admin_email — typically a privacy-proxy address
• source — rdap or whois
• lookup_timestamp

Output streams to an Apify dataset — export CSV, JSON, Excel, RSS, or pull via the dataset API into BigQuery / Snowflake / Looker.

Use Cases

• Domain investors — watchlist of 10k+ domains scored by expiry date for backorder targeting
• Brand protection — daily scan of trademark-typo domains across all gTLDs
• Security / threat-intel — bulk-classify a phishing-feed by registrar + creation date
• Compliance / vendor management — quarterly audit of every domain a vendor uses
• SEO agencies — pre-launch verification that client name servers + expiry are correct
• M&A diligence — pull WHOIS snapshots on every domain a target owns

Quick Start (Python)

from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("nexgendata/whois-domain-lookup").call(run_input={
    "domains": ["openai.com", "anthropic.com", "github.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

FAQ

Q: How is this different from domain-whois-lookup or whois-replacement? A: All three share the same RDAP backend. whois-domain-lookup is the simplest interface (just pass domains, get records). whois-replacement exposes the raw RDAP plus richer fields. domain-whois-lookup is the legacy interface for older integrations.

Q: Why are some registrant fields null? A: Post-GDPR (2018), almost every gTLD registrar redacts personal registrant fields. We return explicit null rather than fabricating values.

Q: Does it support .cn, .ru, .jp, .de, .io? A: Yes — gTLDs go through RDAP, ccTLDs that haven't migrated yet go through a legacy WHOIS fallback. Output schema is identical.

Q: Is bulk WHOIS legal? A: Yes. WHOIS / RDAP is published by ICANN-accredited registries for exactly this purpose.

Q: How fresh is the data? A: Live — every lookup hits the authoritative RDAP / WHOIS server in real time.

Q: Output formats? A: JSON by default, with one-click export to CSV, Excel, or RSS via the Apify dataset UI. Push to Google Sheets / Slack / any webhook with built-in integrations.

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
