Get the price of Bitcoin ¶

The following one liner will retrieve the current price of Bitcoin (in USD) from https://www.bitstamp.net:

<echo>${(fromjson:get:"https://www.bitstamp.net/api/ticker/")['ask']}</echo>

How does this work? Well, the URL https://www.bitstamp.net/api/ticker/ contains a JSON object with the current Bitcoin prices. The get: modifier reads that request from the internet, and the fromjson: modifier converts the text in to a dictionary with a number of values. Finally the index operator ['ask'] looks up the value of 'ask' which is the current asking price.
