Getting Real-time exchange rates for currency - URLFETCH

I'm trying to get real-time currency exchange rates for 1 USD to KRW

To achieve this, I was hoping to urlfetch a google search result

shor url : https://bit.ly/2So7Acz

https://www.google.com/search?q=1+USD+to+KRW&sxsrf=ALeKk01NN-SiwQ8_T3GcC6CKeQ…

and hopefully, possible parse the following span class

< span class="DFlfde SwHCTb" data-precision="2" data-value="1116.335">1,116.34</ span>

to retrieve the data-value.

Can this be done?

$(eval try{a=$(urlfetch ★★★ https://bit.ly/2So7Acz);${parseFloat(a.data-value)};}catch(e){Error!;})
