流式获取会话事件（SSE）

通过 Server-Sent Events 打开会话的实时事件流。

连接在事件到达期间保持打开，在客户端断开时结束。

每个帧包含：

event: 事件的 type，例如 agent.message
id: 恢复游标，可作为 cursor 或 Last-Event-ID 发送
data: 单行的完整 SessionEvent JSON

?cursor=now 仅接收将来的事件，流以一个携带恢复游标的 event: control 帧开始。会话尚无任何事件时，该游标为 0。服务器无法再提供的 cursor 会在流打开前失败，返回 400 invalid_parameter_error。以 : 开头的行必须忽略。流传输失败时发送一个最终的 event: error 帧，随后连接关闭。

下面的示例展示打开时的控制帧和一个事件帧（每个帧以一个空行结束）：

event: control
id: 4096
data: {"cursor":"4096","reason":"tail"}

id: 4128
event: agent.message
data: {"id":"sevt_01","type":"agent.message","processed_at":"2026-01-01T00:00:00Z","data":{"content":[{"type":"text","text":"hi"}]}}

: hb

失败时的终止帧使用 event: error，错误体放在 data: 行上，随后流结束。

请求头

kimi-api-version

enum<string>

本次请求使用的 API 版本，格式为 YYYY-MM-DD。发送 2026-09-01-beta 即使用本文档所述版本。/v1/files* 之外必传：未携带请求头将被拒绝并返回 400 invalid_request_error；在 /v1/files* 上缺省时选择兼容行为。所有端点对未知取值均返回 400 invalid_request_error。平台当前支持的 API 版本。新的日期版本发布时加入；版本在公告的 Sunset 日期后移除。

可用选项:

2026-09-01-beta

Last-Event-ID

string

从上一个 SSE id: 帧之后恢复。两者同时设置时以 cursor 为准。

路径参数

必填

会话 ID。

查询参数

cursor

string

从上一个 id: 帧之后恢复。now 表示只接收将来的事件。

响应
