WhoAPI helps in quickly finding the domain names. It is also used to parse data from active domains such as Alexa ranking, name servers, date of registration and expiration, etc. It covers millions of domains registered worldwide and is extremely affordable.

Its user interface is not much impressive. Also, WhoAPI provides the documentation for the errors that occurred, even though it is a good thing the documentation is heavy-handed. Review collected by and hosted on G2.com.

The best thing while using any third-party APIs from a platform is when something is wrong, it will give some error code in response; so, To understand an explanation for that response error code, WhoAPI has given proper documentation; there were around 42 error codes with description which made easy to understand the errors.

I didn't like the website User interface and also faced issues while registering into the platform, such as even after verifying the mail, it took quite a long to login into the platform. Other than functionality wise, it is working fine. Review collected by and hosted on G2.com.

Really I was amazed after learning about this platform which offers entirely different APIs, and the one that made me feel like that is Screenshot API. User-intuitive modules make us easy to integrate between multiple platforms using methods. Review collected by and hosted on G2.com.

The documentation provided on the site is a bit clumsy, and I am unable to understand correctly to execute integration might need to contact support to get help, which is not easy. Review collected by and hosted on G2.com.

Domain availability checks made easy. WhoAPI also provides many useful, relevant information like hostname, geolocation, network owner. WhoAPI has good documentation and simple implementation. Very intuitive interface. Review collected by and hosted on G2.com.

User-Interface can be improved, but it works fine. Technical Support can be better. It is a little overpriced since it is not a very complex solution. But it delivers what it promises. Review collected by and hosted on G2.com.
