How domain registration works

Coritan registers domains for you with each extension's registry, renews them and hands them over when you move them elsewhere. A domain you register or transfer here is a registration on your account. Its DNS can be hosted on Coritan or anywhere else, because the registration only says which nameservers answer for the domain.

Registration

Your right to a domain for the period you pay for, 1–10 years at a time, held through Coritan.

Registry

The organisation that runs a domain extension, such as .com. Coritan passes your changes to it.

Nameservers

The servers the registry sends resolvers to for the domain. A domain registered here starts on Coritan's nameservers, ns1.coritan.com to ns8.coritan.com.

EPP code

A secret the current registrar gives you so another registrar can take the domain over. It is also called an auth code.

Transfer lock

A registry setting that refuses transfer requests while it is on.

The dashboard shows a domain's price per year when you search for it. A premium domain has a price that its registry sets. View domain prices, in the Websites list's More website actions menu, lists what each extension costs per year to register, renew and transfer. A registration takes the price for the whole period from your account credit before Coritan registers the domain, and gives it back when the registration fails.

A new registration starts with the transfer lock and auto-renew on, and with WHOIS privacy on when you ask for it. The dashboard also offers to issue a certificate and to set up a web proxy for the domain. When either of those is on, Coritan creates the domain's DNS zone too. Register a domain describes each option.

The status appears beside the domain in the Websites list and on its Settings tab. The API sends these words:

Coritan reads each registration back from its registry regularly, and updates its status, expiry date, nameservers and switches from what the registry holds. A change made at the registry shows in the dashboard after that read.

With auto-renew on, Coritan renews the domain for one year when it is within 14 days of its expiry date. With auto-renew off, Coritan emails you 30, 14, 7, 3 and 1 day before the domain expires. Renew a domain covers both.

List your registrations, newest first, with an access token (Authentication). The list takes page, per_page (25 by default, up to 100) and status, which keeps only registrations with that status word:

curl "https://api.coritan.com/api/v1/domains/registrations?status=active" \
  -H "Authorization: Bearer $CORITAN_TOKEN"

{
  "registrations": [
    {
      "id": 7,
      "domain": "example.com",
      "status": "active",
      "registered_at": "2026-09-16T10:04:00Z",
      "expires_at": "2027-09-16T10:04:00Z",
      "nameservers": ["ns1.coritan.com", "ns2.coritan.com"],
      "whois_privacy": true,
      "locked": true,
      "auto_renew": true,
      "dns_zone_id": 42,
      "proxy_route_id": null,
      "ssl_certificate_id": null
    }
  ],
  "total": 1
}

GET /api/v1/domains/registrations/{reg_id} returns one registration in the same shape, or 404 with Registration not found. GET /api/v1/domains/pricing returns the price list, one entry per extension, sorted by extension:

[
  {"tld": "com", "register_price": "14.99", "renew_price": "16.99", "transfer_price": "14.99", "currency": "USD"}
]

The figures in this example only show the shape. The endpoint returns the current prices, as strings, and transfer_price is null for an extension that has none.
