Requests
The web contains a lot of information that LLMs do not have access to. In order to easily let LLMs interact with that information, we provide a wrapper around the Python Requests module that takes in a URL and fetches data from that URL.

Inside the tool
Each requests tool contains a requests wrapper. You can work with these wrappers directly below
# Each tool wrapps a requests wrapper

If you need the output to be decoded from JSON, you can use the JsonRequestsWrapper.
from langchain_community.utilities.requests import JsonRequestsWrapper
requests = JsonRequestsWrapper()
rval = requests.get("https://api.agify.io/?name=jackson")
print(
f"""
Type - {type(rval)}

)
