check_availability
ChatGPTCheck 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.
check_availability_batch
ChatGPTCheck 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.
compare_domain_names
ChatGPTAfter 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.
estimate_cost
ChatGPTEstimate 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.
get_domain_popularity
ChatGPTLook 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.
get_naming_guidance
ChatGPTReturn domain naming criteria, renewal-price comparison guidance and availability-status definitions. This static reference does not generate names or check availability.
get_price_history
ChatGPTReturn 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.
get_registrar_link
ChatGPTConstruct 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.
get_registrars
ChatGPTGet connected registrar coverage, timestamps, fresh counts, failures, and registrars not compared.
get_tld_prices
ChatGPTCompare all covered registrars for one extension. Returns source failures, quote timestamps and minimum terms; availability is not checked.
open_name_finder
ChatGPTOpen 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.
search_prices
ChatGPTCompare standard prices, including explicitly labeled Cloudflare samples. Find affordable domain extensions and registrar offers, sorted by annual renewal by default. Saved offers remain listed when outdated, with stale flags and source timestamps. Returns prices, citation links, timestamps, coverage, and pagination. Does not check exact-name availability.
check_availability
ClaudeCheck one exact name through Cloudflare, then Name.com, Gandi and Fastly when configured, stopping when availability and premium are confirmed. Optional registrar is a final fallback only for remaining facts its connected adapter can confirm and only if that registrar was not already used as leftover (Gandi leftover already covers Gandi; Vercel: availability only). At most one call per leftover stage plus one selected-registrar call; no price lookup. Returns independent availability and nullable premium fields plus provider attempts and times. A missing premium flag means the pricing tier is unconfirmed. No purchase or reservation.
check_availability_batch
ClaudeCheck one name across up to 20 extensions using shared five-minute evidence and the bounded website list pipeline. At most one Cloudflare batch, one packed Name.com batch and three sequential leftover names through Gandi/Fastly; stops enrichment when availability is known. Premium may remain unconfirmed after availability is known. Returns available evidence and retry guidance on partial failure, without automatic retries. cachedOnly makes zero provider calls. No selected-registrar fan-out, fresh mode, prices or purchases.
