I've used Google Spreadsheet as an "API" before (manually, not using this wrapper), and it is definitely not made to be used as such. Under heavy load, it slows down or times out, and even under the best circumstances it's not exactly fast.
It's great in a pinch. My use-case was a spreadsheet that others in my organization wanted to edit, then we'd pull the data onto a web page and display nicely. It worked, but eventually we had to set up a secondary server to cache the spreadsheet result because pulling directly from Google in realtime was too unreliable.
