Basic structure to display simple api endpoint

Hello

I am trying to display a simple bitcon price from the following endpoint:
https://api.cryptonator.com/api/ticker/btc-usd

What I dont understand is the basic structure needed in bootstrap to display the endpoint?

See here my structure:

basic structure347×540 23.1 KB

Do I need to add an additional element below the API Data Source in order the btc-usd price is displayed on a simple page?

I dont find any information in bootstrap on how the API Data Source needs to be embedded.

Thanks for any help -

Thomas
