OpenWeatherMap API
This page covers how to use the OpenWeatherMap API within LangChain. It is broken into two parts: installation and setup, and then references to specific OpenWeatherMap API wrappers.
Installation and Setup
- Install requirements with
pip install pyowm
- Go to OpenWeatherMap and sign up for an account to get your API key here
- Set your API key as
OPENWEATHERMAP_API_KEY
environment variable
Wrappers
Utility
There exists a OpenWeatherMapAPIWrapper utility which wraps this API. To import this utility:
from langchain.utilities.openweathermap import OpenWeatherMapAPIWrapper
For a more detailed walkthrough of this wrapper, see this notebook.
Tool
You can also easily load this wrapper as a Tool (to use with an Agent). You can do this with:
from langchain.agents import load_tools
tools = load_tools(["openweathermap-api"])
