Most of the other modules retrieve data for non-US based securities, or 
specific funds such as TSP.pm for data from https://www.tsp.gov/. 
Fool.pm is one that probably just needs someone to spend a little time 
investigating why it no longer works, but it could be a viable alternative.

People either forget or don't realize that companies like AlphaVantage, 
Yahoo, Alphabet (aka Google), and others pay for the stock market data 
available on their websites or through APIs. Along with what is likely a 
a large cost, there are license limitations on how they may make that 
data available to others. This would be the reason AlphaVantage has 
limits placed on access using the free API key, and probably why Yahoo 
has been blocking access to long utilized URLs/APIs. I fully expect the 
new URL for Yahoo in coming F::Q release 1.56 to get blocked at some 
point. Maybe a few months, maybe a year, but I would bet on it.

This means modules will need to be rewritten to parse the HTML. Doable, 
but not as simple as parsing JSON.
