"Most domain verifiers check the existence of DNS records and parse WHOIS lookup data. Unfortunately, this approach often leads to false positives since many new top-level domain registries don’t return WHOIS records reliably.

In contrast, we talk directly to domain registrars via APIs. This takes a few moments, but the results we get are significantly more accurate."

Nice work.

Any plan for supporting hyphenated domain names?

Thanks for a great suggestion! I've just added that - it should work now. Thanks again!
