check_name ~154 tokens
Look up one .si domain name: whether Hivex lists it as free or likely free, whether it is for sale on Hivex, or whether someone registered it, plus a DNS lookup made now. Returns the name's hivex.si page, where the user runs the final live registry check before registering.
dns_lookup ~214 tokens
Look up the DNS records of any domain or hostname on any extension, live, through Cloudflare's public resolver: A, AAAA, CNAME, MX, NS, TXT, CAA, SOA and more, or the reverse DNS (PTR) of an IP address. Returns the records with their TTLs and the hivex.si page that explains what they mean.
find_names ~335 tokens
Search Hivex's index of .si domain names that are free to register. Filter by a word or fragment (contains, starts with, ends with, exact), length and minimum score; sort by best score, newest or shortest. Returns up to 25 names, each with its hivex.si page.
whois_lookup ~160 tokens
Look up the registration record of any domain, live from its registry's RDAP (the successor of WHOIS): whether it is registered, the registrar, creation and expiry dates, status codes and name servers. Personal details of the holder are never returned. Links to the explained record on hivex.si.
