Right Now, Precious Metals are Hot, Lets Create a Bot

So I have always been curious of metal prices and how they fluctuate with the market.

A couple weeks ago I came across a cool API that can provide metal prices called Metals-Api. This service has a free plan for up to 50 calls per month, which was perfect for my personal use case of sending myself the prices every morning (looks like it could be a great tool for a paid platform as well). I also use telegram and recently also discovered they have a bot API That you can setup to send yourself messages in a Channel.

So I put the two together and combined it with a small node.js program and a cron job on a Digital Ocean Droplet that runs every morning. Low and Behold, metal prices daily!
