## 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](/docs/modules/agents/tools/integrations/openweathermap.html).
|
|
|
|
### 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 tools, see [this page](/docs/modules/agents/tools/).
