Back in May, we announced the deprecation of the free Translate API v1. Today, we’re introducing a paid version of the Google Translate API for businesses and commercial software developers. The Google Translate API provides a programmatic interface to access Google’s latest machine translation technology. This API supports translations between 50+ languages (more than 2500 language pairs) and is made possible by Google’s cloud infrastructure and large scale machine learning algorithms.

The paid version of Translate API removes many of the usage restrictions of previous versions and can now be used in commercial products. Translation costs $20 per million (M) characters of text translated (or approximately $0.05/page, assuming 500 words/page). You can sign up online via the APIs console for usage up to 50 M chars/month.

Developers who created projects in the API Console and started using the Translate API V2 prior to today will continue to receive a courtesy limit of 100K chars/day until December 1, 2011 or until they enable billing for their projects.

For academic users, we will continue to offer free access to the Google Translate Research API through our University Research Program for Google Translate. For website translations, we encourage you to use the Google Website Translator gadget which will continue to be free for use on all web sites. In addition, Google Translate, Translator Toolkit, the mobile translate apps for iPhone and Android, and translation features within Chrome, Gmail, etc. will continue to be available to all users at no charge.

Jeff Chin is the Product Manager for Google Translate. Whenever he travels, Jeff enjoys learning and trying to speak the local language, and finding good local restaurants and food to eat.
