search_prices | Compare standard prices, including explicitly labeled Cloudflare samples. Find affordable domain extensions and registrar offers, sorted by annual renewal by default. Saved offers stay listed after a failed refresh, with stale flags and source timestamps for stating their age. Returns prices, citation links, timestamps, coverage, and pagination. Does not check exact-name availability. params: q, registrar, registrars, favorites, sort, orderBy, direction, years, maxRenewalCents, hideCountryCodes, hideJumps, view, includeStale, limit, offset, name, format |
get_tld_prices | Compare all covered registrars for one extension. Returns source failures, quote timestamps and minimum terms; availability is not checked. params: tld*, registrar, registrars, favorites, sort, orderBy, direction, years, includeStale, limit, offset, name, format |
get_registrars | Get connected registrar coverage, timestamps, fresh counts, failures, and registrars not compared. params: none |
estimate_cost | Estimate new registration plus subsequent renewals for one TLD at a registrar. Returns null for unknown multi-year term totals. Not a transfer or existing-domain renewal quote. params: tld*, registrar*, years*, name |
get_registrar_link | Construct a verified registrar search destination for a proposed name and extension. Does not navigate, check availability, or purchase. NameBright and AWS Route 53 use an explicit copy/paste fallback. params: tld*, registrar*, name* |
get_naming_guidance | Return domain naming criteria, renewal-price comparison guidance and availability-status definitions. This static reference does not generate names or check availability. params: none |
check_availability | Check one exact domain. Cloudflare answers first; configured fallbacks, then an optional selected registrar, run only for missing facts; a taken name ends the chain. Returns separate availability and nullable premium facts, provider attempts and check times; null premium is unconfirmed, not standard tier. Recheck after expiresAt (5 min; up to 30 days if taken). No prices, purchase or reservation. params: name*, tld*, registrar, fresh |
get_domain_popularity | Look up one exact domain in Cloudflare Radar’s global DNS popularity ranking. Returns an exact top-100 rank or a broader popularity group, categories, locations, data dates, and CC BY-NC 4.0 attribution. Not Google SEO difficulty, name competition, or availability. Missing data does not indicate zero competition. params: name*, tld* |
check_availability_batch | Check one name across up to 20 extensions, reusing shared evidence. Enrichment stops once availability is known, so premium can remain null. Partial failures keep the answers received plus retry guidance, without automatic retries. cachedOnly makes no provider calls. No selected-registrar fallback, fresh mode, prices or purchases. params: name*, tlds*, cachedOnly |
open_name_finder | Open the naming form in a compatible host, or return its text workflow. Collect seed names, an optional project brief, count and annual renewal budget; the current assistant generates ideas and checks them with the research tools. Opening performs no generation or registrar checks. Does not connect subscriptions or require a model API key. params: none |
get_price_history | Return how each covered registrar's renewal or registration price for one extension changed over time: price periods with the date each price was first seen, when the previous price was last seen, and whether it came from our scheduled refreshes or the registrar's own price page archived by the Internet Archive. A first record may be older than its date. Availability is not checked. params: tld*, registrar, price, format |
compare_domain_names | After checking exact names with the availability tools, compare up to 10 candidates using saved renewal-first prices and fresh cached evidence. No new availability requests; cache misses are Not confirmed. Returns standard reference offers, premium facts, dates and links. The assistant explains project fit. Split larger lists into bounded groups. Does not generate names. params: domains*, maxRenewalCents |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
