Help Regarding Extra-Life API

So, the time is coming closer for Extra-Life. This will be my second year doing a stream full time and I'm going to be doing two different streams this year: a solo stream and a "teamup" stream with a friend. One thing I couldn't figure out/find last year was an API so could have an image on my stream of how much donations I had been able to get. My work around was to image capture the thermometer on my site and then have that image refresh every 10-15 seconds. I saw some other people, like Brad, had theirs a lot nicer but I didn't see the Extra-Life API was available for use. Any suggestions.
