“WhoisXML API’s Website Categorization API helped me save time. If I did not use it, I would still be categorizing domains manually. It also improved the study’s accuracy, as the API had well-defined categories, and the output is precise and relevant.”

“The website intelligence is easy to set up and returns everything we need. One reason for this is the documentation of the API, which is well-written and very detailed.”

“With other APIs, there’s a tendency for requests to fail. But I didn’t notice that with Website Categorization API. I noticed that whenever a request was made, the website was always categorized.”

“I used WHOIS API and Website Categorization API. Both tools are simple and straightforward to use. Some API providers have extra bells and whistles that they force you to use, but WhoisXML API is really easy to work with. It’s stable, and I can trust that it’s not going to flatline later.”
