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!
See my github repo for more information!

Hello Jordan! My company is just engaged in metal smelting. I think your information will help me, as we are looking for new ways to increase our scale and sales. We produce high-quality metal and alloy, checking it by all means and even spectrometers. Who doesn't know you can watch elvatech.com/applications/pmi/. The device analyzes the quality of the alloy and shows the number of chemical elements in the product.
