AsyncAPI spec endpoints

Fern docs sites serve your raw AsyncAPI 2.6.0 specification at /asyncapi.json and /asyncapi.yaml for sites with WebSocket channels. Download it for client generation, contract testing, or importing into AsyncAPI-compatible tools. The spec is also linked from your site’s llms.txt, so AI coding assistants can discover and use it automatically.
