add the existing OpenWeatherMap tool to the public api (#4292)
[OpenWeatherMapAPIWrapper](dynamic_agent_toolsf70e18a5b3/docs/modules/agents/tools/examples/openweathermap.ipynb) works wonderfully, but the _tool_ itself can't be used in master branch. - added OpenWeatherMap **tool** to the public api, to be loadable with `load_tools` by using "openweathermap-api" tool name (that name is used in the existing [docs](aff33d52c5/docs/modules/agents/tools/getting_started.md), at the bottom of the page) - updated OpenWeatherMap tool's **description** to make the input format match what the API expects (e.g. `London,GB` instead of `'London,GB'`) - added [ecosystem documentation page for OpenWeatherMap](f9c41594fe/docs/ecosystem/openweathermap.md) - added tool usage example to [OpenWeatherMap's notebook](f9c41594fe/docs/modules/agents/tools/examples/openweathermap.ipynb) Let me know if there's something I missed or something needs to be updated! Or feel free to make edits yourself if that makes it easier for you 🙂

# 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"])
|
||||||
|
```
|
||||||
|
|
||||||
|
For more information on this, see [this page](../modules/agents/tools/getting_started.md)
