(APrs). These interfaces act as powerul foois to bhage is problem serves as an introduction to Application Programming Interfaces tabase u are to write a function that returns the stock data to the user in a cell array, given some stock symbol input such as "AAPL This function may be something a future employ ould ask you to write if you are working on an analytical platform for stocks. You will be utilizing an Application Program Interface (API) from Markit to retrieve this data using the uilt-in tunction "webread.- Webread makes an HTTP GET request to Markit given a URL endpoint and a key-value or multiple key-value pairs (kv), he actual coding involved in this programming assignment is minimal and is meant to serve primarity as an introduction to some breadth topics you may find yourseif using in th uture. ssign the tollowing fields from the API response into a cell array. Your ceil array should contain the tollowing data (in order as below): Stock Name, Stock Symbol, Last Price, % Change, and Time Stamp Your Function Reset MATLAB Documenta 1: function data stock-check(symbol) 2 Help: stock_check( 'AAPL) returns relevant stock data about Apple. 4, Markit Quote Endpoint 5 endpoint 'http://dev.markitondemand. com/MODApis/Api/v2/Quote/json; 7、Webread makes an HTTP GET request to Markit's Quote endpoint. 8% webread(endpoint, key, value) % The request parameter for this API call is just the symbol, these 11% are in the form of 'key-value. pairs. Here the key is 'symbol, and the value 12% is a stock symbol (i,e. AAPL). 14 resp. webread (endpoint. 15 symbol); . symbol., Run this code in MAT LAB to determine the output of the API. It should

Answer 1

• endpoint = 'http://dev.markitondemand.com/MODApis/Api/v2/Quote/json';

  the endpoint mentioned is the address where the API "Quote" is hosted.

  resp = webread(endpoint, 'symbol', symbol);

  MATLAB provides the function webread to Get data from URLs and convert it into suitable formats.

  The above command makes a HTTP request and the response is a json which is converted to 1x1 struct.

  data = {resp.Status , resp.Symbol , resp.LastPrice , resp.ChangePercent , resp.Timestamp};

  This code extracts the required fields from the response and create a cell array out of it.
