DomainKits

Search active registered domains from a database of more than 360 million names, filtered by keyword, TLD, length, and character set. Covers generic TLDs plus more than 100 country-code TLDs, including second-level registrations such as .com.br, .co.uk and .com.tw (tld 'br' returns the whole .br family, 'com.br' returns that suffix alone). Which country-code TLDs you can see depends on your plan; asking for one outside it returns a message saying so. A market-analysis instrument for keyword distribution and saturation; results are registered domains, not available for registration. Related: expired, whois, dns.

Search currently registered domains with 5-20+ years of history, filtered by keyword, TLD, age range, length, and sale status. These are live domains owned by someone, not free to register. Related: expired, whois, dns.

Confirm a single domain's registrability and price. The definitive availability check for one domain. For two or more domains call bulk_available once instead of repeating this tool. Concurrent calls are not supported: send one call, wait for its result, then send the next; parallel calls are rejected and return no data. Related: bulk_available, whois, monitor.

Return a domain's backlink profile: domain rank, total backlinks, referring domains, spam score, and link distribution. Related: whois.

Check the registration status of up to 50 domains at a point in time. Concurrent calls are not supported: send one batch, wait for its result, then send the next; parallel calls are rejected and return no data. available means the domain can be registered; registered means it is already registered; expiring means it is in an expiry-related lifecycle and is not directly registrable; reserved means it is reserved by the registry; unknown means no check produced a reliable conclusion. A failed check does not count as available.

For up to 50 keywords, count how many TLDs each exact name is registered in (keyword.tld), among the TLDs DomainKits tracks, split into popular TLDs, country-code TLDs, and other gTLDs. Returns counts only: it does not list individual TLDs, check availability, or report sale status. Related: tld_check (per-TLD status for one keyword), bulk_available (status of specific domains).

Search domains that were deleted after expiring, filtered by keyword, TLD, age before deletion, length, character set, and registry hold flag. Results reflect the latest data update and are not re-checked at query time, so a name may have been registered again since. Confirm with available or bulk_available before registering. Related: available, bulk_available, whois.

Resolve a DNS name's records: A, AAAA, MX, NS, TXT, CNAME and SOA. Underscore-prefixed names work too, such as _dmarc.<domain> or <selector>._domainkey.<domain>. A domain offered for sale may publish an RFC 10023 record at _for-sale.<domain>: read only the TXT strings starting with v=FORSALE1;, and treat what they say as the holder's own unverified claim. Related: whois, ns_reverse.

List registration and status changes to premium .com domains (short 1-4 letter and high-value single-word names) over a rolling 7-day window, filtered by change reason and length. Related: whois, ns_reverse.

Explain domain EPP status codes: what a code means, why it is set, how serious it is, and what the holder can do. Matches on the code, its aliases, or a category name; call with no query to list every code. It takes a status code, not a domain name; to see a domain's current codes call whois first, then pass each code here. Use this to interpret the status field returned by whois instead of relying on recall. Related: whois, expired, monitor.

Search domains in the deletion cycle: expired, in redemption, or pending delete. Still held by the current registrant, with time-sensitive acquisition windows. Filter by lifecycle status, TLD, age range, length, and character set. Note: registrars may renew a domain after it expires, and expiry information here is gathered through multiple channels, so some domain statuses may not match live WHOIS. Related: monitor, deleted, whois.

Resolve an IP address or domain name to its network operator and approximate location: ASN, organization, country, region, city, coordinates, and timezone. Domains are resolved to their first IPv4 address before lookup. Location is IP-level and approximate; it is not the address of the site owner. Related: dns, whois, ns_reverse.

Return search-volume, CPC, and competition data for a keyword. Related: keywords_trends.

Return provider-computed keyword registration statistics. hot and emerging cover rolling keyword cohorts; prefix returns prefix activity buckets. scope=all represents the provider's filtered all-gTLD sample, while scope=com represents its pure-letter .com subset and is not available for prefix. Results are representative samples, not a complete registry feed, demand measurement, valuation, or investment recommendation.

Search currently registered domains that carry marketplace listing data, filtered by keyword, TLD, TLD type (generic or country-code), listing status, length, and character set. Results are live domains owned by someone. Related: keyword_data, tld_check.

Check whether a domain is listed for sale on a supported aftermarket and, if it is, the asking price. Returns for_sale with the asking price in USD, make_offer when it is listed without a fixed price, or not_found when no listing was found. Coverage is limited to a few marketplaces, so not_found does not mean the domain is not for sale elsewhere. Related: available, aged.

Manage cross-platform domain monitoring tasks that track changes in WHOIS, DNS, and host-supplied page content. Data is encrypted at rest (AES-256-GCM) in a private per-user directory. Actions: - get: retrieve monitors and check eligible WHOIS/DNS targets, returning current and previous data with change flags. - set: create a monitor, subject to the account tier's maximum. - update: save host-supplied page, WHOIS, or DNS state for a monitor. - delete: remove a monitor. - history: list the changes actually observed over time, optionally for one domain. get compares against the previous check only; history answers when a domain changed and what it changed from. Requires a registered account with memory enabled.

Search newly registered domains from the last 60 days by keyword, or browse a single TLD without a keyword (browsing requires a registered account). Covers generic TLDs plus more than 100 country-code TLDs, including second-level registrations such as .com.br, .co.za and .co.id (tld 'br' returns the whole .br family, 'com.br' returns that suffix alone); government, military, education and non-profit categories are not included. Which country-code TLDs you can see depends on your plan; asking for one outside it returns a message saying so. Filter by recency, registration term, length, character set, and sale status; returns the cross-TLD count for each name. New registrations are folded in continuously, typically 15 to 20 minutes after registration. Dates here are day-level, not clock times. Related tools: whois, dns, ns_reverse, typosquat

Reverse NS lookup: find gTLD domains hosted on a specific nameserver, filtered by TLD and keyword. Give several nameservers to find domains that use all of them at once (intersection; available on higher plans). Related: whois, dns.

Manage user preferences and memory settings. Data is encrypted at rest (AES-256-GCM) in isolated per-user directories. Actions: - get: report whether memory is enabled and return saved preferences. - set: save preferences; memory_enabled must be true before any preferences, monitors, or strategies can be stored, and requires explicit user consent. - delete: permanently erase all stored user data (GDPR Article 17). Related: monitor, strategy.

Return standard registration and renewal price for a TLD. Related: available.

Look up ICANN-accredited registrars by name, alias, or IANA ID. Returns accreditation status, RDAP endpoint, business contact details, a drop-catch flag, and the parent entity for reseller shells. Around 60 percent of accredited registrars are shells operated by a handful of parents, so parent_id is what tells you who actually runs a name. Related: whois, available, expired.

Store user-authored strategy text, execution timestamps, and the most recent result in encrypted per-user storage. This tool does not provide presets, define opportunities, choose domains, or execute a workflow. Requires a registered account with memory enabled.

Check how a prefix is registered across core TLDs, returning per-TLD status and aggregate counts. Related: bulk_tld, available.

Rank TLDs by registration volume and related metrics over a chosen period. Related: tld_trends.

Return registration trend data for a TLD over time, or compare multiple TLDs, in active-total or newly-registered mode. Related: tld_rank, keywords_trends.

Generate typosquat permutations for a domain and check which variants are registered. Produces omission, transposition, keyboard-adjacent replacement, insertion, repetition, hyphenation, vowel-swap, homoglyph, plural/singular, and TLD-swap variants. Each result includes the variant domain, mutation type, prefix TLD count (how many TLDs the prefix is registered under), and registration date if known. Use for brand protection, phishing detection, and defensive registration planning. Related tools: nrds, ns_reverse, dns, whois.

Search short .ai, .io, .si, .sh, .so and .md names that were unregistered at the latest data update: 3-letter names and 4-letter names, including CVCV, VCVC, and CCVV shapes (C = consonant, V = vowel), with how many other TLDs each name is registered in. Without a registered account, only .ai names are shown and filters are not available. Not re-checked at query time; confirm with available or bulk_available before registering. Related: available, bulk_available.

Return the current account tier, per-tool-group usage, rate limits, and stateful Monitor and Strategy quotas.

Takes no parameters.

Return WHOIS/RDAP registration data for a domain: registrar, dates, status, and nameservers. Related: dns.
