Question 1

How do I check a keyword across all TLDs?

Accepted Answer

Type a keyword, domain name, or URL into the search box above. If you enter a full domain like example.io, the tool automatically extracts the root keyword (example) and checks it across 1,200+ extensions at once. You can then filter the results by TLD category (Popular TLDs, ccTLDs, or Other gTLDs) and registration status (Registered or Possibly Available).

Question 2

Why check a keyword across 1,200+ TLDs, and what does the footprint tell you?

Accepted Answer

While Active Domain Search finds every multi-word variation containing your keyword, TLD Search performs an exact-match horizontal check of a single string across the entire root zone. Reading a keyword's cross-TLD footprint reveals four actionable signals: Demand & Valuation Benchmark: When an exact-match word is registered across 50 to 100+ extensions, it signals proven global demand, a key valuation metric if you are considering buying the .com or .ai on the aftermarket. Category Clustering: Seeing which specific extensions are taken (for example, .ai, .io, and .dev vs. .shop, .store, and .club) immediately shows which industry has claimed the term. Brand & Defensive Gaps: For founders and brand managers, spotting open country-code or core generic extensions lets you lock down key defensive registrations before launch, or before squatters step in. Aftermarket Shortcuts: If your primary extension is taken, the For Sale status and direct marketplace links show whether you can acquire it immediately, and at what price, compared to registering an open alternative.

Question 3

What makes DomainKits TLD Search different?

Accepted Answer

Most registrar search bars only push a handful of promoted extensions and hide aftermarket listings from competing platforms. DomainKits gives you a neutral, market-wide view: Actionable TLD Curation: Rather than padding counts with obscure third-level extensions (like .com.om or .co.ck) that regular users cannot register, we track 1,200+ practically registrable gTLDs and major ccTLDs that represent the vast majority of global domain activity. Registration + Aftermarket in One View: Available extensions display standard registration pricing, while taken extensions flag active marketplace listings with direct purchase links. Vertical vs. Bulk Workflows: Checking one brand name across 1,200+ extensions happens right here; if you need to check a list of keywords against specific TLDs, you can switch directly to Bulk TLD Search. Privacy-First (GDPR): We do not use your domain searches for front-running, and we do not collect or share personal registrant data.

Question 4

Why do some extensions show as "Possibly Available" or restricted?

Accepted Answer

A TLD showing as unregistered in public zone data does not always mean it can be registered at standard cost: Registry-Reserved Names: Many new gTLD and ccTLD registries hold back short, dictionary, or geographic words on reserved lists that cannot be registered through standard channels. Registry Premium Tiers: A registry may classify high-value keywords as premium inventory, charging a higher registration or renewal fee. DomainKits surfaces pricing data where available so you can spot premium tiers upfront. Taken Without a Live Website: Conversely, if a TLD shows as Registered but has no active website in your browser, the domain is still legally held, often parked for brand protection, future development, or resale.

Question 5

Can I integrate DomainKits TLD Search into my workflow?

Accepted Answer

Yes. Everything the search does is available outside the browser: MCP server and Agent Skills: let AI assistants and agents check cross-TLD availability and aftermarket status for you. See MCP and Agent Skills. REST API: query exact-match TLD availability, registration status, and for-sale flags in JSON format for brand-monitoring scripts and internal tools. See the API docs. n8n node and Python SDK: plug TLD checks directly into automated naming and brand-protection workflows. Bulk & Lifecycle Monitoring: scan keyword lists with Bulk TLD Search, or track taken extensions on Domain Monitor with a free account to get email alerts if their status changes.
