from xai_sdk.tool import FunctionTool

# Define a custom tool for weather lookup
def get_weather(location: str) -> dict:
    """Fetch current weather for a given location."""
    # Mock implementation
    return {"temperature": 72, "condition": "Sunny"}

weather_tool = FunctionTool(
    name="get_weather",
    description="Get the current weather for a location",
    parameters={
        "type": "object",
        "properties": {
            "location": {"type": "string", "description": "City and State"}
        },
        "required": ["location"]
    },
    func=get_weather
)

client = Client(api_key=os.environ.get("XAI_API_KEY"))

# Send message with tools attached

    messages=[
        Message(role="user", content="What's the weather like in Austin, TX?")
    ],
    tools=[weather_tool],
    tool_choice="auto"
)

# Check if the model decided to call a tool
if response.choices[0].finish_reason == "tool_calls":
    tool_call = response.choices[0].message.tool_calls[0]

    # Execute the tool locally
    result = get_weather(tool_call.function.arguments["location"])

    # Send the result back to the model
    final_response = client.chat.completions.create(
        model="grok-4.6",
        messages=[
            Message(role="user", content="What's the weather like in Austin, TX?"),
            Message(role="assistant", tool_calls=[tool_call]),
            Message(role="tool", tool_call_id=tool_call.id, content=str(result))
        ]
    )

    print(final_response.choices[0].message.content)
else:
    print(response.choices[0].message.content)
Enter fullscreen mode Exit fullscreen mode
