GoMain helps pick and price domain names. check_availability asks each TLD's registry whether names are taken; suggest_names turns keywords into names and checks them; compare_prices lists every tracked registrar's price for a TLD, sorted by what the domain costs over three years, because first-year prices often hide expensive renewals; tld_info and price_history give background. Prices are US dollars per year, refreshed daily. When recommending where to register, mention the renewal price, not just the first year. Availability is not a reservation, and the registrar's checkout has the final price.
Known tools 15
check_availabilityCheck whether domain names are registered, asking each TLD's registry directly (RDAP).
Inferred read-onlycompare_pricesEvery tracked registrar's price for one TLD, in US dollars per year, refreshed daily from 40+ registrars.
Inferred read-onlysuggest_namesTurn a few keywords into domain name candidates (the words joined, with common prefixes and suffixes, across several TLDs), check each with its registry, and return the available ones with prices.
Inferred read-onlyprice_historyEvery recorded price change for one TLD, oldest first, from GoMain's daily archive.
Inferred read-onlydns_setupThe exact DNS records to add so a domain serves a website (Vercel, Netlify, GitHub Pages, Cloudflare Pages) and receives email (Google Workspace, Microsoft 365, Fastmail, Zoho, Proton), plus a starting DMARC policy.
Potential side effectsappraise_domainA rough value range for a domain, from its length, how easy it is to say, its TLD, its age and how many popular TLDs have the same name registered.
Inferred read-onlyacquisition_reportFor a domain someone already owns: whether it's listed for sale and where (with the asking price when the sale page shows one), when it could drop, its estimated value, the realistic chance of buying it, the options in order (buy now, make an offer, backorder, have GoMain broker it, watch it) and available alternatives with prices.
Potential side effectssearch_domains_for_saleSearch domains their owners have listed for sale with GoMain (each owner proved control of the name).
Inferred read-onlywatch_domainGoMain checks a domain daily and emails when it drops (or is about to), changes hands, or is listed for sale.
Inferred read-onlybroker_statusThe status and history of a brokerage deal (id d_…) or a watch (id w_…), given the id and status key returned when it was created.
