This gives you solid guidance for designing RESTful APIs, from resource naming to status codes to versioning strategies. It's useful when you're sketching out a new API or refactoring endpoints that have gotten messy. The quick start shows good versus bad patterns at a glance, which is honestly half the battle, and the reference guides cover the practical stuff like pagination, filtering, and OpenAPI documentation. The best practices section is opinionated in a helpful way, like reminding you not to nest resources more than two levels deep. It won't make architectural decisions for you, but it will keep you from common mistakes and give you a checklist when you're not sure if you're doing things the standard way.
