JSON → AsyncAPI draft

Client

For HTTP request/response drafts, use JSON → OpenAPI. This page focuses on a single AsyncAPI channel operation (publish or subscribe) with a JSON message payload schema.

Learn more: AsyncAPI vs OpenAPI

Produce asyncapi: 2.6.0 with a single channel operation (publish or subscribe) and a JSON message whose payload schema is inferred from your sample—YAML or JSON output.

Pairs with OpenAPI, not a replacement

OpenAPI describes HTTP surfaces; AsyncAPI describes asynchronous interfaces. Use both pages when a product exposes REST and events, and keep each draft focused on its transport.

One channel only

Real specs list many channels, servers, and security schemes. Treat this output as a starter fragment to paste into a larger file maintained in your repository.

JSON → AsyncAPI draft

?

Infers a JSON Schema payload from your sample and wraps it in one channel with either publish or subscribe—handy next to the OpenAPI draft tool for mixed HTTP and event designs.

Common use cases

  • Bootstrap an event contract next to an OpenAPI service when both live in one repo.
  • Share a subscriber-side sample with agents using the same `q` / `qb` prefill as other JSON generators.
  • Preview how a domain payload might look as AsyncAPI before adding servers and security.

Common mistakes to avoid

  • Treating one sample as the full schema

    Optional fields, unions, and format keywords are not proven by a single paste—tighten components before publishing.

FAQ

Is my JSON uploaded?

No. Inference and document assembly run locally in your browser.
