Embedding Bitcoin share-price into Drupal website?

Hi guys, 

I´ve got a question regarding a Drupal project. I would like to make a website about Bitcoins and within this website, I would like to include the realtime share-price from a website like this (https://coinmarketcap.com/) for example and show the first ten most important currencies of this website on my own website

How would you do this? 
Are there any legal problems to include this on my website?

The website should be just about giving information to users and not about buying or selling bitcoins. 

Thank you very much for your help!

Kind regards TT
