This document discusses the rise of APIs and their widespread use behind cloud services and applications. It notes that the number of publicly available APIs has grown significantly over time, with over 6,000 currently listed. APIs are enabling integration between various software as a service (SaaS) tools, everything-as-a-service, pay-by-call/usage models, and access across many mobile and Internet of Things devices. Companies are also using APIs extensively for internal integrations between their own products and services. The document outlines different business models for APIs, including free/advertising-based or paid subscription approaches.
