API Style Guides

Zalando RESTful API and Event Guidelines

The canonical open community style guide. Maintained by Zalando's API Guild and widely cited as the reference implementation for an API-First, OpenAPI-based REST and event-driven API program. Roughly 150+ numbered MUST/SHOULD/MAY rules covering REST basics, design, operation, and AsyncAPI-style event types.
