AsyncAPI channel · Apache CouchDB · Apache CouchDB _changes Feed

{db}/_changes#feed=continuous

Continuous mode. The HTTP response stays open. Each change is emitted as a single line of JSON (newline-delimited JSON, NDJSON). Heartbeats are sent as empty lines on the `heartbeat` interval. After the configured `timeout`, the server emits a `last_seq` line and closes.

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.
