webhooks.prediction

Outbound webhook callbacks for a prediction. Which of the four event types fire is controlled by the prediction's `webhook_events_filter` array (`start`, `output`, `logs`, `completed`). Default behavior (without filters) fires whenever there are new outputs or the prediction has finished. `output` and `logs` are throttled to at most once per 500ms; `start` and `completed` always send.

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.
