REST API: IP Tracker
Date
Author
A REST API contains information about IP addresses. Given an IP address, make a fetch call to the REST API to fetch its information and find its country of origin.
Perform an HTTP GET request to:
https://jsonmock.hackerrank.com/api/ip?ip=<ip>
where <ip> is the IP address to query.
For example, a GET request to:
https://jsonmock.hackerrank.com/api/ip?ip=172.217.20.46
will return the information for the IP address 172.217.20.46
The response is a JSON object with the following 5 fields:
page: the current page of the results (1)per_page: the maximum number of results returned per pagetotal: the total number of results (1 or 0)total_pages: the total number of pages with results (1)data: Either an empty array or an array with a single IP record object in the following form:ip: IP address [STRING]country: associated country code [STRING]
Below is an example of an IP record:
{
"ip": "172.217.20.46",
"country": "US"
}Please note that you will get the data from page 1 as any given IP just has a single record (if any). Page 1 is the default page returned on an API hit. No further page hits are required.
Given an IP, the goal is to get the country associated with this IP.

import requests
def ipTracker(ip):
# URL for the API request
url = f"https://jsonmock.hackerrank.com/api/ip?ip={ip}"
# Send GET request to the API

# Check if the request was successful
if response.status_code == 200:
# Parse the JSON response
data = response.json()
# Check if any record is returned
if data['total'] == 0:
return 'No Result Found'
# Extract the country code from the record
country = data['data'][0]['country']
return country
else:
# Request failed, return an error message
return 'API request failed'
