]no-highlight]=<API key>
 & text[no-highlight[The text to translate.
You can use multiple text parameters in a request. 
Attention! The source text must be URL-encoded. 
Restrictions:
For POST requests, the maximum size of the text being passed is 10,000 characters.
In GET requests, the restriction applies not to the text itself, but to the size of the entire request string, which can contain other parameters besides the text.
The maximum size of the string is from 2 to 10 KB (depending on the browser version).
]no-highlight]=<text to translate>
 & lang[no-highlight[The translation direction.
You can set it in either of the following ways:
As a pair of language codes separated by a hyphen (“from”-“to”). For example, en-ru indicates translating from English to Russian.
As the target language code (for example, ru). In this case, the service tries to detect the source language automatically.
]no-highlight]=<translation direction>
 & [format[no-highlight[Text format.
Possible values:
plain - Text without markup (default value).
html - Text in HTML format.
]no-highlight]=<text format>]
 & [options[no-highlight[The only option available at this time is whether the response should include the automatically detected language of the text being translated. This corresponds to the value 1 for this parameter.
If the language of the text being translated is defined explicitly, meaning the lang parameter is set as a pair of codes, the first code defines the source language. This means that the options parameter does not allow switching to automatic language detection. However, it does allow you to understand whether the source language was defined correctly in the lang parameter.
