Domainr is the only ICANN-accredited domain status API provider.

With direct, privileged access to domain registry data, the Domainr API instantly checks if a domain is available—with no false positives. In milliseconds, your customers will know if a domain is available, premium-priced, or for sale in any major aftermarket.

If you’re a security provider or manage a software supply chain, the Domainr API can help you monitor critical domains, alert you to any changes to their status, and uncover at-risk domains before they change hands.
