# Server-Sent Events stream of RunEvent frames

GET

/v1/runs/{runId}/stream

```sh
curl --request GET \
  --url https://example.com/v1/runs/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/stream \
  --header 'Authorization: Bearer <token>'
```

Each SSE frame is one `RunEvent` per `@kindgi/specs/run-event.schema.json`. Reconnect via `Last-Event-Id: <runId>:<sequence>`. The server ends the stream after the run’s terminal event, or after 5 minutes: reconnect with `Last-Event-Id` to continue.
