Precious Metals API
Live precious and industrial metal spot prices as an API — gold, silver, platinum, palladium and copper — with optional currency conversion via European Central Bank rates. Get the live USD spot price of any metal and convert it into any major currency; list them all at once; compute the value of a quantity of metal; or read the classic gold/silver and gold/platinum ratios traders watch. Built for trading, jewellery, treasury and dashboard apps. The commodities and precious-metals layer, live and key-free — distinct from generic ticker-quote APIs.
