Stream Function

Stream a function call execution in real-time using Server-Sent Events (SSE).

This endpoint returns a continuous stream of Server-Sent Event objects as the function executes, allowing for real-time streaming of responses. The response follows the Server-Sent Events specification with proper event structure for SDK compatibility.

Each Server-Sent Event contains:

• id: Optional event identifier
• event: Optional event type
• data: JSON payload with streaming chunk information
• retry: Optional retry interval

The data payload includes:

• delta: Incremental text content (if any)
• span_id: Unique identifier for the execution span (when available)
