description: >-
  Topic index for the AsyncAPI ecosystem — the open specification, tooling, and
  adopter community for describing event-driven and message-driven APIs. AsyncAPI
  is to asynchronous APIs what OpenAPI is to synchronous REST: a machine-readable
  contract describing channels, operations, messages, servers, and protocol
  bindings (Kafka, MQTT, AMQP, WebSocket, NATS, SNS, SQS, JMS, Pulsar, IBM MQ,
  ROS 2, and more). This repo catalogs the specification versions, the canonical
  tooling (Studio, Parser, Modelina, Generator, CLI), validators (Spectral,
  Microcks, Apicurio Registry), code-first frameworks (Springwolf, FastStream,
  nestjs-asyncapi, AsyncAPI.NET), and real-world adopters (Adeo, HDI Global,
  TransferGo, Walmart, LEGO, eBay, Salesforce).

- name: AsyncAPI Specification
  description: >-
    The AsyncAPI Specification is an open-source machine-readable format for describing asynchronous APIs.
    It defines channels (the addressable message endpoints), operations (send/receive actions an application
    performs), messages (the payload schema), servers (the broker connection details), and bindings (protocol-specific
    details for Kafka, MQTT, AMQP, WebSocket, NATS, SNS, SQS, and others). Version 3.0 (December 2023)
    introduced a major restructuring separating operations from channels; version 3.1.0 (January 2026)
    added ROS 2 bindings.
