“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.”
