Web APIs are central to today’s applications. They provide interfaces that are easily consumed by apps written in any programming language on any platform. They make complex technologies simple by exposing easy-to-use, intuitive interfaces that enable app developers to weave together incredible experiences quickly.
To leverage and understand an API, documentation becomes a critical necessity. Specifications like OpenAPI 3 enable APIs to be described in a standard format that can easily be rendered e.g. as interactive, HTML documentation.
