Write a PL/SQL function to call API -- 2

Hi, I need a function that from within Oracle Database calls an API to get the current currency rate from fixer.io. Code is written in PL/SQL API Access Key is provided. This is the example code prvided from [login to view URL] to do the job in PHP: <?php // set API Endpoint and API key // Initialize CURL: $ch = curl_init('[login to view URL]'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Store the data: $json = curl_exec($ch); curl_close($ch); // Decode JSON response: $exchangeRates = json_decode($json, true); // Access the exchange rate values, e.g. GBP: echo $exchangeRates['rates']['GBP']; ?>
