Extract value from the JSON response using the API

Using the jsonpath-ng library to extract values from the JSON response. jsonpath-ng is a fork of the jsonpath library and allows for more powerful querying of JSON data using expressions similar to those used in XPath.

# install jsonpath-ng library
pip install jsonpath-ng

Here’s an example of how you could use jsonpath-ng to extract the conversion rate from the JSON response in the first example:

Python3

# import required libraries
import urllib.parse
import requests
from jsonpath_ng import jsonpath, parse
 
# setting the base URL value
baseUrl = "https://v6.exchangerate-api.com/v6/0f215802f0c83392e64ee40d/pair/"
 
# ask user to enter currency values
First = input("Enter First Currency Value: ")
Second = input("Enter  Second Currency Value: ")
 
# combine base URL with final URL including both currencies
result = First+"/"+Second
final_url = baseUrl+result
 
# send API call and retrieve JSON data
json_data = requests.get(final_url).json()
 
# set up jsonpath expression to select conversion rate
jsonpath_expr = parse('$.conversion_rate')
 
# use jsonpath expression to extract conversion rate
result = jsonpath_expr.find(json_data)[0].value
print("Conversion rate from "+First+" to "+Second+" = ", result)

Output

Using jsonpath-ng can make it easier to extract specific values from complex JSON structures without having to manually navigate through the data.
