This project repository is a web based calculator API that leverages Python and Flask to perform standard mathemical calculations such as addition, subtraction, multiplication and division.

This API is hosted at the following URL: https://calcapp.herokuapp.com/results

This API has two endpoints:

• /operate
• /results

This is used to perform the calculator operations and return the results in JSON format following the request.

Input:

CURL -X GET https://calcapp.herokuapp.com/operate?operations9*981

Output:

{
  "operation": "90*891",
  "result": 80190,
  "updated_date": "Mon, 12 Oct 2020 16:51:20 GMT"
}

API usage is explained below:

Addition: (must use '%2b' instead of a '+' sign when forming the request)

CURL -X GET https://calcapp.herokuapp.com/operate?operations4%2b4

Multiplication, division and subtraction:

CURL -X GET https://calcapp.herokuapp.com/operate?operations4*4

CURL -X GET https://calcapp.herokuapp.com/operate?operations4/4

CURL -X GET https://calcapp.herokuapp.com/operate?operations4-4

You can either navigate to the following URL or request programatically using curl. This endpoint is designed to output in JSON and only show the last 10 calculations, the results with a date/time stamp recent to oldest.

CURL -X GET https://calcapp.herokuapp.com/results

Using a browser, navigate to: https://calcapp.herokuapp.com/results

Note: Refreshing the results endpoint requires a browser refresh at this time.
