Integrate third party content using API

I need a third party content service integrated in one of my sites using their API (the current setup is in PHP and JSON). This should be a seamless integration and pretty straightforward for anyone proficient with PHP and API integration. I will provide the links and information for the feed, and need it to be integrated in a mockup page that I will provide. After that, I should be able to easily copy the code to my own site where the feed should be integrated. In other words, you will need to set this up for me on a mockup site so that I can essentially copy and paste the code onto my own site and have it working. Payment will be made once the integration is verified as working on my own site. To make sure you have read these instructions, please include the answer to the following question in your bid, "what color is the sky?". Any other questions or clarification please ask.
