Get a quick WHOIS review for all domain names on the web page.
The WHOIS XML API Plug-in automatically adds a tool-tip with summarized WHOIS information. It also adds a link to a public report, for all domains in the post-text and comments, on our website: <a href="https://whoisapi.whoisxmlapi.com/" rel="nofollow ugc">https://whoisapi.whoisxmlapi.com/</a>.
The tooltip appears when a user hovers the cursor over a domain name in the text. You can then click on the link to conduct a more in-depth study of the domain’s WHOIS record.
The integration of the tooltip is seamless and the WHOIS XML API Plug-in does not modify the content in any way. You are able to turn it off at any time, and all of the text will revert to its original format.
If you have any additional questions that have not been covered, please feel free to email us at <a href="mailto:support@whoisxmlapi.com" rel="nofollow ugc">support@whoisxmlapi.com</a>. We will do our best to get back to you within 1 business day.
