Sitey — free subdomains

Check if a specific subdomain name is available for registration under a given domain. Returns true if the name is free to claim.

Create 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. The target does not have to be serving yet: claim the name first and deploy to it second if that is your order. The result carries reachable:false when nothing answered, and the record is created either way. If you send no owner_token, the result carries a new one under 'owner_token' — save it, it is shown once and is the only way to change or delete this record later. Without an API key, a CNAME or REDIRECT may not point at a temporary tunnel (trycloudflare.com, ngrok and the like), names containing words such as login or wallet are refused with ACCOUNT_REQUIRED, and TXT records are not available.

Create 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 is the name Vercel reads for a subdomain of sitey.my. Needs an account: send an API key from the dashboard (Authorization: Bearer styo_…) on the MCP request. Without one this returns ACCOUNT_REQUIRED.

Permanently delete a subdomain DNS record you own. The subdomain will stop resolving immediately.

Delete a TXT verification record from a subdomain you own.

Paying 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.

List available root domains (e.g. sitey.my, sitey.one) that you can create subdomains under. Call this first to know which domains are available.

List 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_token you pass, or — for records made before tokens existed — by your IP address.

Extend 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 today. Renewal only opens in the last two weeks before expires_at — an earlier call is refused and tells you the date it opens.

Update 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.
