Trying to parse json from Coinmarketcap to get Bitcoin price.

Hello, I'm still pretty new to unity but have a firm grasp on most things. Getting Json from an external site and decoding it seems to have me confused. Can anyone give me a quick code example on how to decode this. Is it possible with unity's built in Json tool since is set up as an array?

Here is he json I want to fetch and decode.

https://api.coinmarketcap.com/v1/ticker/bitcoin/

I would only like the "price_usd" of Bitcoin.

Thanks for your help!
