Parse value to shortcode or widget

Hello, is it possible to parse a value to the widget so the currency converter will widget will show different currencies depending on the page currently shown. For example: example.com/eur will show EUR and example.com/gbp will show GBP currency to something else that is static?
Example shortcode:
[ccc_currency_converter_calculator lg=”en” tz=”1″ fm=”EUR” to=”DKK” st=”info” bg=”FFFFFF” lr=”” rd=””][/ccc_currency_converter_calculator]

Thanks.
