Batch-check up to 1,000 keywords or domain names across 1,400+ TLDs.

Pick the tool based on what is in your clipboard and what question you are trying to answer:

• Use Bulk TLD Search to Measure Keyword Demand: Best when you want to know how popular or competitive each word on your list is. You can paste bare words (like "agent" or "payflow") or full domains from an auction export, and Bulk TLD Search strips the extensions automatically and counts how many TLDs each root label is registered in across Popular, ccTLD, and gTLD buckets.
• Use Bulk Domain Check to Verify Exact Domains: Best when you have a list of full domain names with specific extensions (like example.ai, example.com, or example.io) and want Bulk Domain Check to show which ones are available, already registered, listed For Sale on the aftermarket, or Expired.

Whether you are filtering daily auction sheets or brainstorming a new brand name, four baseline workflows help turn a raw list of 1,000 entries into a short list of winners:

• The Two-Step Drop List Filter (Bulk TLDs → Bulk Domains): Paste an auction or expiring domain list into Bulk TLD Search first and sort by Total TLDs. Once you isolate the keywords with strong Popular and ccTLD adoption, test their .com, .ai, .io, and .co variations in Bulk Domain Check.
• Validating AI-Generated Brand Names: When an LLM generates 100 coined startup name ideas, paste them into Bulk Domain Check. Read the TLD count on each Available row to find names that are open in your target extension but already registered across other TLDs.
• Spotting Aftermarket Shortcuts (For Sale & Expired): When checking a wish list of exact domains in Bulk Domain Check, a taken name can still be within reach. Filter your batch results by For Sale to jump straight to marketplace listings, or by Expired to catch domains entering the drop cycle.
• Pre-Purchase History Triage (Wayback & Check Details): Before bidding on a taken domain from your batch, open its Lookup menu to inspect Wayback Machine snapshots, or click Check Details in Bulk TLD Search to see every extension taken for that keyword in TLD Search.

Running batch queries requires a DomainKits account:

• Member (Free Account): Check up to 100 keywords or domains per batch. Each batch uses 4 of your daily searches. Create a free account to start.
• Paid Plans: Raise your batch size up to 1,000 entries at once, with higher daily search limits (see pricing).

Yes. If you need full daily lists rather than list checking, you can download daily registration lists on the NRD Download page. To run batch keyword and domain checks from AI workflows, use the MCP server or Agent Skills; the REST API offers bulk WHOIS and bulk DNS lookups for your own scripts.
