Title: how are you pulling JSON from exchanges?
Post by: Tasty Champa on August 26, 2011, 09:31:07 PM

Every time I look at the page source of tickers, order books and charts, I don't see anything.
Is this all happening with SSI?

It's all happening with AJAX and Websockets/Socket.IO

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/api

If you call the page directly with your browser you will get something like this;

{"ZAR":"62.78"}

In PHP you can do this;

Code:

<?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.

What exchanges are you looking to extract JSON data from?

I have written libraries for some exchanges already. See my sig
