AsyncAPI Specification

The AsyncAPI Specification (AAS), is a specification for a programming language-agnostic, machine-readable interface definition language for describing, producing, consuming, and visualizing event-driven services.

AsyncAPI documents describe API services and are represented in YAML or JSON formats.
