Other than functionality wise, it is working fine. **What problems is WhoAPI solving and how is that benefiting you?** It gives 10,000 requests for free signup, which are useful for deciding whether we can rely on this API or not. Also, the services provided by this platform I have never seen Screenshot API in any API marketplace before. ### 3.

WhoAPI also provides many useful, relevant information like hostname, geolocation, network owner. WhoAPI has good documentation and simple implementation.
