OpenAPI Specification

asyncapi-diff-api-openapi.yml Raw ↑
openapi: 3.2.0
info:
  title: AsyncAPI Server Bundle Diff API
  version: '1.0'
  description: 'The AsyncAPI Server API exposes the official AsyncAPI tooling

    (validation, parsing, conversion, code generation, bundling, diffing)

    over HTTP. It is open source under the AsyncAPI Initiative (now part of

    the AsyncAPI CLI repository) and can be self-hosted via Docker.


    Note: The AsyncAPI specification itself is a documentation/specification

    standard, not an API. This document covers the companion AsyncAPI Server

    API which provides the runtime HTTP surface.
