tld_check
ActiveTool of DomainKits
Check a keyword prefix's registration status across all TLDs. Returns total registration count (gTLDs + ccTLDs) and status of core TLDs (com, net, org, io, ai, de). This is a saturation and popularity metric — the total count indicates how widely a keyword has been claimed across the TLD namespace. Interpreting results: - count >200: Keyword is widely recognized — either high market demand or strong brand protection (or both). Cross-reference with keyword_data and active to determine which. - count 50-200: Worth attention — check if there are still opportunities available. - count <50: Not a particularly popular keyword in the domain market. - gtlds_count vs cctlds_count ratio: High ccTLD registration suggests international interest in the keyword. The tlds field shows status for core TLDs (com, net, org, io, ai, de) with values: 'registered', 'for_sale', 'expiring', or 'might_available'. Note that 'might_available' means the prefix is not found in our database for that TLD — confirm with the 'available' tool before assuming registrability. Best practices: - The prefix parameter must NOT contain the TLD extension — use 'openai' not 'openai.com'. - If .com shows 'might_available' for an established keyword, this is unusual and worth verifying. - If .com shows 'for_sale' or 'expiring', this is a potential acquisition opportunity worth flagging.
