Domain Reseller API

Register and manage domains for your customers automatically. The API is free – no one-time or monthly fees, you only pay the domain prices. DNS hosting and DNSSEC are included, hosted in the EU.

curl -X POST https://www.cloudzaro.com/api/v1/domains \
  -H "Authorization: Bearer cz_live_…" \
  -H "Content-Type: application/json" \
  -d '{"domain":"meinefirma.de","contact_id":12}'

Everything resellers need

Availability

Binding check at the registry, up to 10 endings per call.

Register & transfer

Order with one call, poll the status. Auth code for moving away via API as well.

Holder handles

Create and update persons and companies, assign them to domains.

DNS records

Create, update and delete A, AAAA, CNAME, MX, TXT, SRV, CAA and NS – with validation and warnings.

DNSSEC

One call turns DNSSEC on or off; the key is published at the registry automatically.

Renewal

Automatically by card before expiry – or set to "let expire" via API.
