+```python

+from agent_framework_ag_ui import AGUIChatClient
+
+async def main():
+    async with AGUIChatClient(endpoint="http://localhost:8000/") as client:

+                    print(content.text, end="", flush=True)
+        print()
+
+asyncio.run(main())
+```
+
+The `AGUIChatClient` supports:
+- Streaming and non-streaming responses
+- Hybrid tool execution (client-side + server-side tools)
+- Automatic thread management for conversation continuity
+- Integration with `ChatAgent` for client-side history management
