`/`

The root WebSocket channel multiplexes every subscription and every control envelope. Clients publish `SubAdd`/`SubRemove` action messages and subscribe to the union of welcome, lifecycle, heartbeat, error, and data envelopes the server emits.

About AsyncAPI

The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.

Browse every event-driven channel on the APIs.io network or compare with the broader Agent Skill and MCP server surfaces of the same providers.
