# Stream one thread's events (SSE)

`GET /v1/agent-runs/{runId}/threads/{threadId}/events`

Server-Sent Events stream filtered to one conversation: replays durable events with `seq > after` whose `thread_id` matches, then attaches live. Same frame shape as the run-wide stream (`id: <seq>`, `event: <type>`, `data: <AgentEventEnvelope>`). The run-wide `GET .../events` carries every thread; this one carries a single `threadId`. Not rate-limited (long-lived stream).

## Path parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `runId` | `string` | Yes |  |
| `threadId` | `string` | Yes |  |

## Query parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `after` | `integer \| null` | No | Replay cursor. Replays this thread's durable events with `seq` strictly greater than this value, then attaches live. Defaults to 0. |

  path: { runId: "...", threadId: "..." },
})
```

## Responses

**`200`** — An event stream for one thread. The body is `text/event-stream`; each `data:` line is one `AgentEventEnvelope` JSON object.

**`401`** — No valid session cookie or `wbl_*` bearer was present. Returns `ApiErrorEnvelope`.

**`404`** — No thread visible to the caller with this id in this run (`AGENT_THREAD_NOT_FOUND`). Returns `ApiErrorEnvelope`.

**`422`** — Path param failed UUID validation (`INVALID_PARAMS`). Returns `ApiErrorEnvelope`.
