Open Weather Map Tool

This tool connects to the OpenWeatherMap's OneCall API, using the pyowm Python package. You must initialize the tool with your OpenWeatherMap API token

The tool has access to the following functions:

• the current weather
• the weather tomorrow

Usage

Here's an example usage of the OpenWeatherMapToolSpec.

from llama_index.tools.weather import OpenWeatherMapToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

tool_spec = OpenWeatherMapToolSpec(key="...")

agent = FunctionAgent(
    tools=tool_spec.to_tool_list(),
    llm=OpenAI(model="gpt-4.1"),
)

print(await agent.run("What is the temperature like in Paris?"))
print(await agent.run("What is the wind like in Budapest tomorrow?"))
