Mastering API Architecture: Design, Operate, and Evolve API-Based Systems

This book shares an architect's view of developing and deploying APIs. They discuss the major components that go into an API architecture and some of the technologies that apply to each one.They use a couple of the architect's tools throughout, specifically C4 diagrams and Architecture Decision Records (ADRs). The ADRs are particularly effective as they evolve the architecture of the example API throughout the chapters.The book is well done and a useful reference.
