/language

This request handler enables you to set the target language (to translate to), and also to detect the source language of a web domain or block of text. It expects any of the following parameters:

• sl = to set the source language (if requesting a list of machine translation servers)
• tl = to set the target language (it will set a cookie, tl, on the user's browser)
• domain = to detect the language associated with a web domain (e.g. lemonde.fr)
• text = to detect the language for a block of text (auto detection)

if you use this API call to detect the source language, it will return the source language code (2 or 3 letter ISO code), or a blank response if it cannot detect or guess the language.
