Bulk WHOIS Lookup: Domain Expiry & Availability (RDAP)

Bulk WHOIS Lookup checks hundreds of domains in one run through each registry's official RDAP service: registrar, creation and expiry dates, days until expiry, nameservers and whether the domain is available. $0.0015 per domain, failed lookups free.

How to use it

1. Paste your domains (full URLs and www. are fine).
2. Turn on Only output available domains if you're hunting for free names.
3. Click Start and export the results as Excel, CSV or JSON.

What you get for each domain

Field	Example
status / available	registered / false

Features

• 1,200+ TLDs through the IANA RDAP bootstrap list (.com, .net, .org, .uk, .au, .app, .dev and most new gTLDs)
• Classic port-43 WHOIS fallback for ccTLDs that have no RDAP service yet
• Accepts messy input: full URLs, www., upper case, duplicates
• "Only available" mode for domain hunting and brainstorming lists
• Lookups that fail (timeouts, registry errors) are returned with an error and not charged

Use cases

Expiry monitoring for a domain portfolio, checking which brand-name ideas are free, lead enrichment (domain age and registrar of prospects), brand-protection and lookalike-domain checks, SEO and expired-domain research.

Notes

RDAP data is published by the registries for public lookup; some registries (for example DENIC for .de) limit how their data may be reused, so check the registry's terms for your use case. Registrant names, emails and addresses are usually redacted under GDPR/ICANN policy; this tool returns only what the registry publishes. "Available" means the registry has no record of the domain; premium or reserved names can still be unavailable to buy.

Input example

{
  "domains": ["apify.com", "wikipedia.org", "my-new-brand-idea.com"],
  "onlyAvailable": false
}

How much does it cost to check 1,000 domains?

Pay per event: you pay only for results.

Example: 1,000 domains cost $1.50; 100 cost $0.15.

Apify also charges its standard run-start fee of $0.00005 per GB of run memory (a fraction of a cent per run). The exact prices are always on the Pricing tab, and you can cap any run with Maximum cost per run.

FAQ

Do I pay for failed lookups? No. Timeouts and registry errors are returned with an error and not charged.

Why is the registrant name missing? Most registries redact registrant details under GDPR/ICANN policy; this tool returns only what the registry publishes.

Does available mean I can buy it? It means the registry has no record of the domain. Premium or reserved names can still be unavailable.
