I do not have coding related problem here. I want some details about currency converter API.
$l_json_from = $this->currency->format($total_row['value'], false, false, false);
$l_url = "http://rate-exchange.appspot.com/currency?from=INR&to=USD&q=$l_json_from";
$l_jsons = @file_get_contents($l_url);
$l_json_data = json_decode($l_jsons, true);
$l_to_cur = $l_json_data['v'];
I have used this above code to convert the INR rate into USD rate using this URL. Yesterday it’s working fine. But, today it doesn't work. Rate exchange API URL says:
Over Quota
This application is temporarily over its serving quota. Please try again later.
Why this site shows like this? What is the reason? Shall I try any other currency Converter API?
