# 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](https://openweathermap.org/api/)
|
||
|
|
- 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:
|
||
|
|
|
||
|
|
```python
|
||
|
|
from langchain.utilities.openweathermap import OpenWeatherMapAPIWrapper
|
||
|
|
```
|
||
|
|
|
||
|
|
For a more detailed walkthrough of this wrapper, see [this notebook](../modules/agents/tools/examples/openweathermap.ipynb).
|
||
|
|
|
||
|
|
### Tool
|
||
|
|
|
||
|
|
You can also easily load this wrapper as a Tool (to use with an Agent).
|
||
|
|
You can do this with:
|
||
|
|
|
||
|
|
```python
|
||
|
|
from langchain.agents import load_tools
|
||
|
|
tools = load_tools(["openweathermap-api"])
|
||
|
|
```
|
||
|
|
|
||
|
|
