4 About this guide The developer's guide describes the and explains how to enable and use the service. The guide is intended for web developers who want to add the text translation feature to pages on their web sites. API description Attention! Starting from version 1.5, all API methods must be accessed using a key. Please fill out this simple form to get your free API key. To access the over HTTPS, there are XML and JSON (JSONP) interfaces available. All the interfaces provide identical functionality and use the same set of input parameters. The XML interface returns a response in the form of an XML document, while the JSON interface returns JavaScript objects instead of XML elements, but with the same names and semantics; the JSONP interface returns the same JavaScript objects, but by calling a callback function with the specified name. Formatting results When formatting translation results, you must follow the rules set in the License for using the Yandex.Translate service. Each page that uses data from the Yandex.Translate service must display the text "Powered by Yandex.Translate" with an active hyperlink to the page http://translate.yandex.com/. The font size for the link must be no smaller than the font size for the main text, and the color must match the font color of the main text on the page.

API methods 7 detect method Detects the language of the specified text.
