"WHOIS API Making Brand Protection a Breeze"
5/5
What do you like best about Whois API Webservice?

WHOISXML API’s WHOIS API has been a great tool that helps my company protect its digital assets. With its wide coverage of the Internet—billions of WHOIS records; thousands of TLDs, including newly created gTLDs, and millions of domains—we get fairly accurate search results when seeking out information on our own and our clients’ domains. Because its database is well-parsed and well-structured, we know we’re getting WHOIS records that are consistent in formatting and so can be easily compared with one another. It makes brand protection a breeze for us with additional useful features like Brand Monitoring as well. With it, we can easily spot possible causes for concern such as copyright violators and copycats. Review collected by and hosted on G2.com.

What do you dislike about Whois API Webservice?

WHOIS API search results come in 2 download formats—JSON and CSV. We made the mistake once of choosing the JSON format and it was a little tough to read since we didn’t have the proper applications. But now that we’re using the CSV files instead, we’re no longer having the same difficulty. Review collected by and hosted on G2.com.

"WHOIS Data that Helps Enhance Site Security"
5/5
What do you like best about Whois API Webservice?

As not-so-technical users, raw logs intimidate us and XML and JSON files can be a little hard to read. Thankfully, Whois XML API allows us to view results for WHOIS, IP, and DNS records in .csv or even online through their web-based platform. This gives us more straightforward findings that we can use to enhance website security. Review collected by and hosted on G2.com.

What do you dislike about Whois API Webservice?

Due to private registrations or hidden details, some WHOIS and IP records can lack information. Because of that, we can’t really make instant decisions about certain domains and IPs (e.g., allow or blacklist them) and understand the most likely intent of users.
