Event-Driven Channels
Browse every channel inside every official AsyncAPI specification published by an API provider on the APIs.io network. Each channel is the named pipe — webhook URL, Kafka topic, WebSocket route, MQTT subject — that producers and consumers publish to or subscribe from, with structured message payloads.

What's a channel? The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. Where OpenAPI has paths, AsyncAPI has channels — the routes that messages flow over. Each channel carries one or more message types, and an operation declares whether a party publishes or subscribes on that channel. This site indexes every channel inside every AsyncAPI spec on the APIs.io network, with per-provider rollups and per-channel detail pages that cross-link to the provider's other agent surfaces.
