As folks who power real-time APIs, my team is always interested in broader trends in what is referred to as the “API Economy." In the last couple of years, we (and everyone else) have seen the proliferation of APIs skyrocket. ProgrammableWeb indexes over 18, 412 APIs. Even Walgreens has an API.
This has generally been a good thing for developers who want to build new technology. Instead of having to build your app from scratch, you can assemble distributed processes for everything from payments to messaging that are built and scaled by specialists, leaving you with more time to focus on your unique functionality. There are APIs and "as-a-services," for almost everything you can imagine – and this means developers are implementing more APIs in a single project than ever before.
