# Single-turn session

> Example 3: Session - send one message, stream response

Demonstrates creating a conversational session, sending a single message,
and streaming the response token by token using listen() with event filtering.

```python theme={"languages":{}}
import asyncio

from vectorshift.agent.tools import ExaAiTool, GoogleSearchTool
