Bulk Domain Availability Checker (RDAP): Names x TLDs

Check thousands of domain names across any TLDs at once, with no login, no browser and no code. Export to JSON, CSV or Excel, or use the API.

Check thousands of domain names across any TLDs at once: available or registered, plus registrar, creation and expiry dates, days to expiry, status codes and nameservers for taken domains. Uses official registry RDAP with a DNS fallback. Enter brand ideas plus TLDs (.com, .io, .ai...) or full domains.

Use cases

• Brainstorm brand names and see which .com/.io/.ai are free
• Monitor competitor or wish-list domains for upcoming expiry
• Clean a list of domains into registered vs. unregistered

Input

Field	Type	Notes
names	array	Bare names are combined with every TLD below; full domains are checked as-is.
tlds	array	Applied to bare names.
onlyAvailable	boolean
maxConcurrency	integer

Example input

{
 "names": [
  "realtourmedia",
  "zzqx-brand-idea-8812",
  "therealtour360.com",
  "google"
 ],
 "tlds": [
  "com",
  "io",
  "ai",
  "co.uk"
 ]
}

Output

One dataset item per result. Main columns: domain, status, available, registrar, created, expires, expiresInDays, nameservers, method, error. A RUN_SUMMARY record is saved to the default key-value store. See the sample output in the Output tab.

Notes

available means the registry has no registration (RDAP 404). likely-available means the TLD has no RDAP and DNS returns NXDOMAIN. Premium or reserved names can still be unavailable or cost more, so confirm at a registrar before you buy.

Example output

{
  "domain": "realtourmedia.io",
  "name": "realtourmedia",
  "tld": "io",
  "status": "likely-available",
  "available": true,
  "method": "dns",
  "expiresInDays": null
}

Pricing

Pay per result, with no monthly rental or subscription:

• Domain checked: $0.0005

Example: 1,000 results cost about $0.50 in fees. Apify's free plan includes $5 of monthly credit, which is enough to test this Actor.

FAQ

Do I need an account, cookies or a login for the source site? No. Bulk Domain Availability Checker uses public data sources only, so there is nothing to connect and no account to risk.

How much will a run cost? You pay only for results delivered (see Pricing above), plus Apify platform usage, which the free plan's monthly credit easily covers for test runs. Start with a small limit to see the exact cost per run.

Can I export to CSV, Excel or Google Sheets? Yes. Every run's dataset can be downloaded as JSON, CSV, Excel, XML or HTML, or pushed to Google Sheets, Make, Zapier, n8n, Slack or a webhook through Apify integrations.

Can I run it on a schedule or from my own code? Yes. Add an Apify Schedule (hourly, daily, weekly) or call it through the Apify API / Python & JavaScript clients. It also works with AI agents through the Apify MCP server.

What happens if an input is invalid or a source is down? The run keeps going. The bad input gets a row with an error field so you can see what failed, and you are not charged for results that were not delivered.

Is this legal to use? It collects publicly available data. You are responsible for using the output in line with the source's terms and privacy laws such as GDPR/CCPA; don't use it for spam.

Something missing or broken? Open an issue on the Issues tab. Feature requests are usually added within a few days.

Scheduling / monitoring

Create a Schedule (daily/weekly) and connect a webhook or Slack/email integration.

Fair use

Official public APIs only, no login. Do not use output for spam or harassment. Respect the data sources' rate limits and terms.
