A solid reference for REST API conventions that covers the essentials: resource naming with plural nouns, proper HTTP method usage, status code selection, and response formatting. Shows good versus bad URL patterns, includes a clean table of when to use 200 versus 201 versus 204, and demonstrates pagination and filtering with query parameters. The JSON-API inspired response format with data, meta, and links is opinionated but clean. Use this when you're designing a new API from scratch or trying to get your team aligned on consistent conventions. It won't make architectural decisions for you, but it will keep you from reinventing basic patterns or mixing POST and GET semantics.
