EventSource mode. Same semantics as `continuous` but framed as Server-Sent
Events (`text/event-stream`). Each change is delivered as an `event: ` /
`data: ` block, with `id:` set to the row's `seq`. Heartbeats are emitted
as SSE comment lines. The endpoint honors the `Last-Event-ID` header for
reconnects.
Stream SSE-framed change events on a long-lived HTTP response.

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.
Calls without X-API-Key need no key. Calls with it need a paid plan — get a key.
