Domain WHOIS & DNS Lookup: Bulk RDAP, Age, Expiry, MX, SPF

Domain WHOIS & DNS Lookup checks domains in bulk and returns, for each one: the registrar, creation and expiry dates, domain age, days until expiry, status codes, nameservers, DNSSEC and whether the domain is registered at all (a quick availability check). It adds the DNS and email setup next to that: A/AAAA records (does it have a website?), MX records, the email provider behind them (Google Workspace, Microsoft 365, Zoho…), the SPF record and the DMARC policy. Paste domains, website URLs or email addresses, or point it at any Apify dataset of leads or companies, and the columns are added next to each item.

Why this Actor

• Official sources. Registration data comes from each registry's RDAP service (the modern, structured replacement for WHOIS, listed by IANA). For TLDs without RDAP (for example .io, .co and .de), it falls back to the registry's WHOIS server.
• Polite and reliable. It sends at most 3 requests at a time to any one registry, retries when a server is busy (honouring Retry-After), and reports any failure in an error column instead of dropping the row.
• Privacy-minded. It returns the registry-level facts (registrar, dates, status, nameservers). It never collects the names, emails, phone numbers or addresses of domain owners.
• Takes messy input. https://www.Shop.example.co.uk/page, sales@example.com and EXAMPLE.com all become the registered domain (it understands multi-part suffixes such as .co.uk). With Look up each domain once, 500 emails from the same company cost one lookup.

Use cases

• Lead qualification: company age, whether the website is live, and whether they use Google Workspace or Microsoft 365, for every lead a scraper finds.
• Email deliverability checks: SPF and DMARC policy for a list of sending or prospect domains.
• Domain portfolio and expiry monitoring: schedule a daily run on your domains and filter daysUntilExpiry below 30.
• Availability checks: registered: false means the registry has no record of the domain.
• Brand protection: check look-alike domains for registration date, registrar and nameservers.

How to use it

1. Add Domains, URLs or emails, and/or pick a Dataset to enrich. For datasets, set Domain fields if yours aren't named domain, website, url or email.
2. Choose what to look up: Registration data and/or DNS and email setup (both are on by default).
3. Run it. Each domain becomes one output row. Export as CSV, Excel or JSON, or chain it with an integration.

Input example

{
  "domains": ["apify.com", "https://www.wikipedia.org", "sales@example.co.uk"],
  "includeWhois": true,
  "includeDns": true
}

Output example (shortened)

{
  "domainInput": "apify.com",
  "domain": "apify.com",
  "tld": "com",
  "registered": true,
  "source": "rdap",
  "registrar": "Amazon Registrar, Inc.",
  "registrarIanaId": "468",
  "createdAt": "2009-06-02T17:14:10Z",
  "expiresAt": "2035-06-02T17:14:10Z",
  "domainAgeDays": 6344,
  "daysUntilExpiry": 3152,
  "status": ["client transfer prohibited"],
  "nameservers": ["ns-1225.awsdns-25.org", "ns-449.awsdns-56.com"],
  "dnssec": true,
  "hasWebsite": true,
  "mxRecords": ["aspmx.l.google.com", "alt1.aspmx.l.google.com"],
  "emailProvider": "Google Workspace",
  "spfRecord": "v=spf1 include:_spf.google.com ~all",
  "dmarcPolicy": "reject",
  "error": null
}

Other columns: updatedAt, aRecords, aaaaRecords and whoisServer (set when the WHOIS fallback was used). A run summary is saved as OUTPUT in the key-value store.

How much does it cost?

Pay per event: $0.0025 per looked-up domain (one output row), plus a $0.001 run start fee. Platform usage is included. These are free: repeats skipped by Look up each domain once, domains left out by Output only registered domains, rows for input that isn't a domain, and lookups that failed (registered: null with an error), so re-running failed rows doesn't cost twice.

Apify Store discounts: the price above is for Apify's Free plan. Paid plans pay less per 1,000 looked-up domains: $2.18 on Starter, $1.75 on Scale, $1.38 on Business. The "from" price at the top of the Store page is the Business price.

Worked examples:

Examples use the Free-plan rate. Where an example doesn't add it, each run also has its run-start charge, counted per GB of Actor memory (minimum one; one at the default memory); Apify Proxy (where used) is billed separately.

• 1,000 company websites: 1,000 × $0.0025 + $0.001 = $2.501.
• A daily expiry check of 20 domains: $0.051 per run, about $1.53 per month.

If you set a maximum cost per run, the Actor stops cleanly at that limit.

FAQ

Some fields are empty for my .de / .io / .co domain.

Those registries don't run RDAP, and their WHOIS servers publish less. DENIC (.de), for example, shows nameservers and status but no creation or expiry dates. The Actor returns what the registry publishes.

What does "registered": null mean?

The registry couldn't be reached or didn't answer clearly (see error). Re-run those rows later; registries sometimes rate-limit.

Why no owner name or email?

Most registries redact them under GDPR, and this Actor deliberately doesn't collect personal contact data.

Is "Self-hosted" or "Other" email provider a problem?

No. "Self-hosted" means the MX records point at the domain itself; "Other" means a provider outside the built-in list.
