As expected from an "ideas" book, the text is peppered with first person thoughts, rhetorical questions, and very strongly held opinions (e.g., "REST beat SOAP" and "JSON beat XML".) If you buy into these, the book will feel natural and even inspired. If you don't, your hackles may get a workout.
Nevertheless, it ultimately does what any good "ideas" book should do - stimulates your thinking.
From a conceptual perspective, this book provides stellar explanations on topics that are must-knows for REST-practitioners. E.g., on the differences between protocol semantics and application semantics; and the relevance of HATEOAS when it comes to the semantic web.
A minor disappointment for me was that the "API" in the title was defined at a higher-level than I'd have liked. At its core, it merely proposes that a new API should not be a custom one-off, but instead should use standards whenever possible. As a result, it focuses on explanations of standards such as those that deal with collections, URI Templates, and hypermedia controls. However, it punts on the more prosaic elements of good REST API design - such as the identification of resources and operations, for a given domain.
This book's contents could also have benefited from better organization. Concepts were spread out geographically, and often needed a lot of paging back and forth to assemble a complete picture.
Despite these minor quibbles, I thoroughly enjoyed the read.
While this book could be read by a developer at any level, it would be most appreciated by a technical lead or architect who is already familiar with basic REST concepts. Beginners to this technology might be better served by Bill Burke's RESTful Java with Jax-RS - which also covers low level API design adequately. (Note that there is an updated edition due shortly.)
It's very clearly written and accessible, and doesn't require too much knowledge to dive into. For reference, I started learning programming around 3 years ago through my current college major.
Here's the Cliffs Notes version:
The problem that the author approaches is that APIs these days are not consistent with one another or even with themselves. This causes several issues:
1) APIs are inflexible. Once you release them, it's very difficult to change them. This is ironic, since HTTP and the web is powerful because of its flexibility.
2) APIs are not machine-readable. You have to read prose documentation to figure out how they work, and every API is different. At the same time, API documentation is often not up to date or non-existent, and it's unscalable to expect all API developers to maintiain complete documentation for all the APIs that they ever work.
3) People create novel, non-standardized APIs for the same general tasks over and over again. There's a staggering amount of repeated work.
The hope is that following standards and imposing structure and metadata in your APIs will one day allow API clients to bridge what the author calls "the semantic gap," which amounts to making an API self-document itself by using standardized idioms and good RESTful web practices, a pattern that the author calls "hypermedia."
The book lays out the problems, solutions, and process of following good API practices clearly, as well as the kind of work that needs to happen to flesh out hypermedia. In this day and age I think anyone who is writing APIs should read this book first, for the betterment of all—programmers, users, and businesses alike.
