Developers: API & Embed Widget

Registry-direct availability data for your project, and a checker widget for your site — free for fair use.

Availability API

Check any domain with a simple GET — JSON response, registry-grade accuracy:

GET https://namizy.com/api/check?domain=example&tld=com

{
  "domain": "example.com",
  "available": false,
  "status": "registered",
  "registrar": "RESERVED-Internet Assigned Numbers Authority",
  "creation_date": "1995-08-14",
  "expiration_date": "2026-08-13",
  "check_time_ms": 142,
  "check_method": "rdap"
}

Also available: GET /api/whois?domain=example.com for full parsed RDAP records (registrar, dates, nameservers, status codes, DNSSEC). Supported TLDs: com, net, org, io, co, dev, app, me, xyz, info via RDAP; ai, ly, tv, cc, gg, to via DNS fallback (marked in check_method).

Embeddable checker widget

Drop a working domain checker into any article, sidebar or tool page — one iframe, no JavaScript dependencies, dark theme included:

<iframe src="https://namizy.com/embed/checker"
        width="100%" height="180" frameborder="0"
        title="Domain availability checker — Namizy"></iframe>

Fair use, plainly

This service is funded by the affiliate links in our own UI, so the API is offered as-is for reasonable interactive use: prototypes, internal tools, content sites, student projects. Sustained bulk scraping, resale of the data, or traffic that threatens stability gets rate-limited without ceremony. If you're building something bigger, talk to us — we like interesting integrations.

Frequently asked questions

Do I need an API key?

No — fair-use access is open: stay under roughly 1 request/second sustained and identify your project in the User-Agent. Responses are CDN-cached for 5 minutes. If you need volume guarantees, get in touch via the contact page.

Where does the data come from?

Directly from each TLD's authoritative RDAP server (Verisign for .com/.net, PIR for .org, Google Registry for .dev/.app, etc.), with DNS fallback for TLDs without RDAP. No third-party databases in between.

Can I embed the checker on a commercial site?

Yes. The iframe widget is free to embed anywhere, including commercial sites, as long as the 'powered by Namizy' attribution link stays visible and unmodified.
