Secure authentication, lightning-fast JSON responses, 724+ TLDs, full .af support, embeddable widget, commission pricing, and more — all in one free REST API.
Everything you need to add domain availability checking to any website, app, or platform — from a one-line widget to a full REST API integration.
Every API request is authenticated with a unique client key. Keys are scoped per client, can be rotated, and support origin-based restrictions.
Each client gets an independent rate-limit bucket. Exceeding it returns HTTP 429 so you can gracefully degrade.
The only domain API with complete Afghanistan ccTLD support — all .af sub-TLDs including .com.af, .net.af, .org.af, .gov.af, and .edu.af.
A simple GET request returns a structured JSON response with availability, pricing, and purchase link — works with any language or framework.
Drop a fully-functional domain availability search box onto any page with a single line of HTML. No backend code required on your end.
<div> + one <script>Pull live domain registration prices from the API backend pricing feed and apply a commission markup. The API returns display prices and a ready-to-use purchase URL.
commission_percent per requestredirect_url for checkoutQuery live WHOIS data for any domain — registrar, registrant country, creation and expiry dates, nameservers, DNSSEC status — returned as clean JSON.
Resolve DNS records — A, AAAA, MX, NS, TXT, CNAME, SOA, CAA, SRV — for any domain. Query multiple record types in a single API call.
Check up to 10 domains in a single request. Send a JSON array by POST or a comma-separated list by GET. Perfect for domain investors and portfolio tools.
Enter a keyword and receive up to 20 smart domain name suggestions across the best TLDs — prefixes, suffixes, splits, .af variants. Perfect for brand discovery.
Every request is validated in three steps. Invalid or disabled keys receive a 403 before any WHOIS lookup occurs.
The client_key is looked up in the database. Unknown or disabled keys are rejected immediately.
If an allowed-origins list is set for the client, the request Origin header is validated against it.
The per-minute request counter for the client is checked and incremented. Exceeding returns HTTP 429.
The response includes availability status, optional live pricing with commission applied, and a ready-to-use purchase button URL — all in one call.
