These things are not really on the same level. Google usually gives more than a years notice, and always has a way to export your data. These guys are shutting down in the month and it looks like the only help you get with your data is a link to a gist on github.
The Google API I was using had a 6 month lead time, no recommendations for graceful transition, no offer of data dumps, and the final shutdown date was never communicated.
The API I was using, was shutdown without any communication. (Adsense for ajax - announced at Google I/O 2010). They simply closed my account without paying the money I was owed (substancial sum). I later found out from a Gooler "yeah they decided to shutdown the product".
Beware of relying on anyone, even a big company who says they won't be evil.
I am in the middle of moving an API over from a Google one that got shutdown recently. This has cost me a substantial chunk of time, more than it likely has cost you.
I'm viscerally aware of inverterate corporate capacity for volatility.
