Attach to a session and stream its canonical event ledger over Server-Sent Events (SSE). The stream includes user messages, status changes, assistant output events, tool lifecycle events, and webhook diagnostics in session order. The stream stays open while the session is reusable, including while the session is idle. Reconnect with Last-Event-ID to resume after the last event you processed.

​
Path Parameters

​
session_id
string
required
Session ID.

​
Headers

​
Authorization
string
required
Bearer token using your Dari API key.
​
Accept
string
Should be text/event-stream.
​
Last-Event-ID
string
Optional SSE resume cursor when reconnecting.

​
Streaming behavior

Each SSE event uses the same canonical event envelope returned by GET /v1/sessions/{session_id}/events. The SSE id is the event ID, and the SSE event is the event type. Representative event types include user.message, session.status_changed, message.status_changed, assistant.message_completed, tool.call_requested, tool.call_completed, tool.call_failed, tool.result_submitted, and webhook.delivery_failed.
