This reads like a bunch of buzzwords to me. Maybe I’m the wrong audience for this post. The way I see it APIs aren’t products or services. They are implemented by products and services.
Also, what is meant by API rating? APIs aren’t exchangeable like restaurants. I can’t just use API B because API A doesn’t have enough stars. If I want to process some data from Tumblr or Facebook I have no choice but using the official one.
And what’s API management? Overseeing the addition of methods to it?
