AsyncAPI is a community-driven project aimed at enhancing the landscape of Event-Driven Architecture (EDA). Our vision is to simplify the process of working with EDAs to the same level of ease as interacting with REST APIs. This encompasses various aspects, including documentation, code generation, event discovery, management, and much more. The AsyncAPI Specification establishes a universal, protocol-independent framework that outlines message-based or event-driven APIs. By utilizing the AsyncAPI document, both individuals and machines can grasp the functions of an event-driven API without needing to delve into the source code, access documentation, or analyze network traffic. This specification enables the definition of API structures and formats, along with the channels available for end users to subscribe to and the message formats they will receive. Furthermore, you have the ability to develop, validate, and transform your AsyncAPI document to the most current version, or preview it in a more user-friendly format through the AsyncAPI Studio, making the entire process more intuitive and accessible. Ultimately, our mission is to foster a more cohesive and efficient experience in the realm of event-driven interactions.

Levo.ai provides enterprises with unparalleled visibility into their APIs, while discovering and documenting all internal, external, and partner/third party APIs. Enterprises can see the risk posed by their apps, and can prioritize it based upon sensitive data flows and AuthN/AuthZ usage. Levo.ai continuously tests all apps and APIs for vulnerabilities as early as possible in the SDLC.
