Tools 10 found in our last check
list_domainsList available root domains (e.g. sitey.my, sitey.one) that you can create subdomains under. Call this first to know which domains are available.
check_availabilityCheck if a specific subdomain name is available for registration under a given domain. Returns true if the name is free to claim.
create_subdomainCreate a new DNS record for a subdomain. Supports A records (IP address), CNAME records (hostname) and REDIRECT records (an https:// URL — visitors to the name are sent there with a 301). Example: create demo.sitey.my pointing to 1.2.3.4. No account, API key or signup is needed.…
list_subdomainsList all subdomains you own. Returns subdomain name, domain, record type, value, and creation date. A REDIRECT record also carries hits: how many visits it has answered in total, how many this calendar month, and when the last one was. Filtered by your API key, or by the owner_t…
renew_subdomainExtend a subdomain you own before it expires. Subdomains are lent for a period, not given: agent-created records last one month and user records three. Nothing emails an agent, so read expires_at from list_subdomains and call this before that date. One call resets the clock from…
extend_subdomainPaying for a year is switched off on this server, so this always answers PAYMENT_DISABLED. Use renew_subdomain, which is free and adds a month.
update_subdomainUpdate the DNS record value of a subdomain you own. For example, change the IP address that demo.sitey.my points to. The new target does not have to be serving yet; the result carries reachable:false when nothing answered, and the record is moved either way.
delete_subdomainPermanently delete a subdomain DNS record you own. The subdomain will stop resolving immediately.
create_txt_recordCreate or update a TXT record for domain verification. Used for services like Vercel (_vercel) and Netlify that require DNS-based ownership proof. The record is placed at the root domain under the prefix you give (e.g. _vercel.sitey.my), alongside the other owners' values — that…
delete_txt_recordDelete a TXT verification record from a subdomain you own.
