Google has announced they'll be limiting and eventually shutting down the Google Translate API, meaning any iPhone or iPad apps that rely on the service for free translation functionality aren't going to be able to reply on it any longer.
The Google Translate API has been officially deprecated as of May 26, 2011. Due to the substantial economic burden caused by extensive abuse, the number of requests you may make per day will be limited and the API will be shut off completely on December 1, 2011.
Google Translate is a great, free-as-in-Google web-based language translation service that can tell you what a seal is in French or what ferme means in English. The API let developers use that free service in other web apps, or in native apps like those in iOS. Which is what Marco Armant guesses just might have been the problem.
I wonder how Google felt about all of these iPhones hitting their free translator constantly. Seems like the kind of service that they might want to be exclusive to Android. Maybe iPhone apps are the “abuse” they’re talking about.
Microsoft's Bing still offers a free translation API, so developers have an alternative, for now at least. It's another example, however, of how risky it can be to base your app on the goodwill and free offerings of a big internet company like Google, Twitter, or Facebook.
