I am trying to use the Coinbase API to pull live bitcoin data to my Wordpress site and display the exchange rate. I want to achieve something similar to this: http://preev.com/
There are a few things I would really appreciate help with: 1. How to extract bitcoin rate against other currencies from the Coinbase API? 2. What do I need to replace in my wordpress theme file to display the information on the page?
I am new to using API's and any help would be much appreciated.
Personally what I would do is get a wordpress plugin that allows you to make PHP widgets.
Then simply put the appropriate PHP and CSS code, to display your data.
Here are some good php widget plugins.
