You find the URL for the API - see below, this is for getting the South African Rand price of Bitcoin
http://www.bitcoin.za.org/apiIf you call the page directly with your browser you will get something like this;
{"ZAR":"62.78"}In PHP you can do this;
<?php
$_rate = file_get_contents("http://www.bitcoin.za.org/api");
$obj = json_decode($_rate);
$_rate = $obj->{'ZAR'};
echo "ZAR = $_rate";
?>
This will result in;
ZAR = 62.78
Hope it help you or someone.
