Tools

• acquisition_report ~136 tokens
  For 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 av
• appraise_domain ~112 tokens
  A 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. Use it to set a realistic budget before trying to buy a taken name. Not a comparable-sales appraisal.
• broker_status ~87 tokens
  The 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.
• check_availability ~207 tokens
  Check whether domain names are registered, asking each TLD's registry directly (RDAP). Returns registered, available, likely_available (no registry lookup service, but no DNS records either) or unknown, plus the registrar and dates for taken names and the cheapest prices for open ones. Up to 20 name
• check_name ~147 tokens
  Is a project name usable everywhere it'll be needed? Checks the domain across TLDs (with prices), GitHub, npm, PyPI and crates.io, and gives links for trademark and social-handle checks that can't be automated.
• compare_prices ~188 tokens
  Every tracked registrar's price for one TLD, in US dollars per year, refreshed daily from 40+ registrars. Sorted by 3-year cost (first year plus two renewals) by default, because a cheap first year often hides an expensive renewal. Each offer links to where to buy.
• dns_setup ~240 tokens
  The 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. Checks live DNS to show which records are already in place and warns about clashes s
• list_domain_for_sale ~209 tokens
  List a domain the user owns for sale. The first call returns a DNS TXT record that proves ownership; once it's added, calling again with the same domain and email activates the listing. asking_price is shown to buyers; floor_price, the lowest offer accepted automatically, never is. Sales close throu
• make_offer ~226 tokens
  Offer to buy a domain listed with GoMain. Offers at or above the asking price buy it outright; lower offers are negotiated automatically with a counter-offer, for up to three rounds, then the seller decides. An accepted offer opens an Escrow.com transaction, so the money is only released once the do
• price_history ~171 tokens
  Every recorded price change for one TLD, oldest first, from GoMain's daily archive. A registrar's first entry is its price when the archive began (or when it started selling the TLD); later entries are changes. Prices are per year, in US dollars unless `currency` says otherwise.
• request_acquisition ~231 tokens
  Ask GoMain's brokerage to acquire a domain someone else owns. GoMain researches it, approaches the owner without naming the buyer, negotiates within the budget (which the owner never sees), and closes through Escrow.com. Confirm the buyer's email and budget with the user before calling. Returns a de
• search_domains_for_sale ~116 tokens
  Search domains their owners have listed for sale with GoMain (each owner proved control of the name). Returns asking prices where set; make_offer buys or negotiates.
• suggest_names ~204 tokens
  Turn 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. For your own name ideas, use check_availability.
• tld_info ~116 tokens
  Who runs a TLD, its type (generic, country-code, ...), when it was delegated, its registry's website and lookup servers (from IANA), and its cheapest first-year, renewal and 3-year prices.
• watch_domain ~96 tokens
  GoMain checks a domain daily and emails when it drops (or is about to), changes hands, or is listed for sale. Returns a watch id and status key for broker_status.
