Tools (10)

compare_tld_pricesUse this when the user asks what an extension costs or where it is cheapest. Returns every registrar's register, renew, transfer and restore prices for one TLD, ranked by the N-year cost of ownership (default 3 years), with each price's source and date.
cheapest_registrarUse this when the user wants the single best place to buy (or transfer) one or more extensions for N years. Ranks by the total cost of ownership, not the first-year promotion; returns the winner with a year-by-year breakdown, three runners-up and caveats. Up to 20 extensions in one call.
total_cost_of_ownershipUse this when the user compares the long-run cost of several names or extensions, at one registrar or the cheapest. Applies minimum terms and regular renewals; with transfer_after_year it also finds the cheapest registrar to move to later. Up to 20 domains or extensions in one call.
check_availabilityUse this when the user asks whether specific domain names are free. Checks the registry (RDAP, WHOIS for some ccTLDs) after a DNS pre-check, with an honest unknown, and adds the cheapest registrar's price to own each free name. Up to 50 names in one call.
search_name_across_tldsUse this when the user has a name and wants to know which extensions are free and what each costs to own. Checks one label across up to 50 extensions (or a preset: popular, tech, cheap, country:<cc>) and sorts the free ones by total cost.
suggest_namesUse this when the user needs name ideas. Pass `candidates` from your own brainstorm and we check and price them; with only `keywords` we add simple prefixes, suffixes, TLD hacks and combinations. Returns only names that are available or unknown, cheapest first.
get_registrarUse this when the user asks about a registrar: its country, group, size (gTLD domains under management), how many extensions it sells, and how fresh our prices for it are. Accepts our id, its name or an IANA id.
price_historyUse this when the user asks how an extension's prices have moved or whether a rise is coming. Returns each registrar's price periods (changes only) and the registry's announced wholesale changes.
list_couponsUse this when the user asks for promo codes, coupons, deals or first-year discounts. Returns coupon codes as each registrar's own API or promotions page lists them (code, operation, extensions, discount, limits, end date, last seen at the source, an example price with the code), and running promotio
get_tldUse this when the user asks what an extension is, who runs it, or whether it fits: type (generic or country code), registry, brand TLD or not, DNSSEC, RDAP and WHOIS servers, minimum term, second levels, registry fees, and its price summary.
