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"])
