Register, transfer, renew and manage 500+ domain extensions from one REST API. You get wholesale rates, we stay out of the way. Set your prices, keep the difference, and run the whole thing from your own site, WHMCS or Blesta.
Already reselling somewhere else? Move your domains over and manage everything from one key.
Everything below is a single call away. No registry contracts, no accreditation, no waiting on a sales rep.
Check availability, register, transfer, renew and manage domains with clean JSON endpoints. Bearer-token auth, predictable responses, real error messages.
You pay reseller rates below retail across the whole catalog. Whatever you charge your customers on top is yours to keep.
From .com, .net and .org to .io, .cc, .ws, .to and a long list of country-code and niche TLDs. One integration covers all of them.
Set custom nameservers, apply defaults in bulk, and manage A, AAAA, CNAME, MX, TXT, SRV and CAA records through the API.
Turn privacy on or off per domain on supported TLDs so your customers stay out of the public WHOIS.
Pull EPP/auth codes, lock or unlock a domain, and transfer names in with a single request.
Read and replace the registrant contact on any domain you own without leaving the API.
Fund your balance with Bitcoin, Monero, USDT and more. Cards and PayPal work too. Every order draws from your prepaid credit.
Manage domains, funds, API tokens and usage from your account, with the same data the API returns.
Most resellers are registering their first domain within the hour.
Grab the Domain Reseller API package from the client area. Activation is instant.

Point WHMCS, Blesta or your own code at the API. Import the WHMCS module or follow the PDF guide.
Register domains for your customers at wholesale, set retail prices, and keep the margin.
Authenticate with a bearer token, post the domain, and the cost comes off your balance. The same pattern covers transfers, renewals, DNS and privacy.

Get API accessHOSTCAY runs from the Seychelles, a privacy-friendly jurisdiction, so you can offer domains without becoming an accredited registrar yourself. You get direct wholesale access to the catalog and full automation, and your customers never see who is behind it.
There is no contract and no minimum. Fund your balance when you want, register when you want, and stop when you want. Because everything runs through the API, you can plug domains into an existing hosting brand or build a standalone marketplace on top of it.
We do not ask for ID, and we do not hand your data to third parties. Pay in crypto and stay private from signup to renewal.
Every step is an API call, from availability to renewal.
Wholesale in, your retail price out. The spread is yours.
No KYC, no documents, no data sharing.
Order, tokenise, integrate. Minutes, not weeks.
