AsyncAPI Server API

The AsyncAPI Server API is the only callable HTTP API the AsyncAPI Initiative operates. It exposes the official AsyncAPI toolchain — validate, parse, convert, generate, bundle and diff — over HTTP at https://api.asyncapi.com/v1, free, keyless and without signup. It is stateless: every operation takes an AsyncAPI (or OpenAPI 3.0) document in the request body and returns a derived document, diagnostics or service metadata. The same service is self-hostable via Docker or `asyncapi start api`.

AsyncAPI Server API is one of 9 APIs that AsyncAPI publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Event-Driven, Specification, Tooling, Validation, and Code Generation. The published artifact set on APIs.io includes an OpenAPI specification and an API reference.

This API exposes 8 operations across 8 paths, organized into 8 resource areas, and defines 20 schemas. It is described by OpenAPI 3.1.0, at version 0.2.0.

Requests are made against a single base URL, https://api.asyncapi.com/v1.

Where this information came from

This is an independent, third-party profile of AsyncAPI Server API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
