load sample data from the selected API at least two times $($chose an interval between those requests based on the pace of the data change$).$ Create a single $.$CSV file that would include all the data provided by the API in two or more requests. Make sure to label each record provided by an API with the time of the request. Also, include column$($s$)$ that will show the difference of at least one value that occurred between the requests.

For example, if a Weather API returns a JSON file with the current temperature in $10$ cities, convert data to $.$CSV$,$ which when combined would have at least $20$ records $(2$ for each city based on two requests$),$ add an additional column with the time of the request, and a column showing the difference between the temperature during the second and the first request.
