Openapi Expert

If you're designing REST APIs or need to document existing ones, this gives you comprehensive OpenAPI 3.1 guidance with working examples. It covers the full spec including paths, schemas, security schemes, and reusable components, so you can generate client libraries, validate requests, and maintain actual API contracts instead of outdated wiki pages. The examples show real patterns like pagination, JWT auth, and proper error responses. Honestly, the spec itself has a learning curve, but once you're past the YAML verbosity, having machine-readable API definitions beats manual documentation every time. Best for teams that need consistent API design or want to automate SDK generation.
