A cryptocurrency app

I would like to make an app where you can follow prices etc. of cryptocurrencies. I am trying create a label with a changing text depending on how the price is changing on the site. The photo shows what i am trying to do. So it has to be somehow connected to the site but I have no clue how to extract the data, implement it and transform it into simple numbers. Can somebody help? kryptooo

  1. First of all you need a free or paid API from where you can get those data.
  2. Second you need to use Web component for getting those data through API call.
  3. Third if your Cryptocurrency tokens list is static then you need to drag that number of label on screen then change text value of label component using blocks.
  4. And if the number of tokens are dynamic then you need to use dynamic components extension and for that you need to search extension in community.
