Domain API Guide

Integrate Domain Services Into Your Platform

Our Domain API lets developers, resellers, and SaaS platforms programmatically register domains, manage DNS, check availability, and automate renewals — all through a clean, documented REST API.

POST /domains/check
// Check domain availability POST /api/v1/domains/check { "domain": "mybrand.com", "extensions": [".com", ".net", ".org"] } // Response { "status": "200 OK", "available": true, "domain": "mybrand.com", "expires": null, "price": "contact_sales" }
API Capabilities

What the Domain API Supports

A comprehensive set of endpoints covering every aspect of domain lifecycle management — from availability checks to full DNS control.

Domain Availability Check

Query availability for single or multiple domains and extensions in real time. Get pricing and registration eligibility in one API call.

Domain Registration

Register domains programmatically with registrant contact details, nameserver configuration, and registration period selection.

Domain Transfers

Initiate and monitor domain transfers using authorization codes. Track transfer status through API responses and webhooks.

DNS Record Management

Create, update, and delete A, AAAA, CNAME, MX, TXT, SPF, and NS records through the DNS management API endpoints.

Renewal Automation

Automate domain renewals, set auto-renew preferences, and receive expiration webhook notifications before domains lapse.

Lock & Security Controls

Enable or disable registrar locks, manage WHOIS privacy settings, and update domain security configurations programmatically.
