Gold Price APIs
Gold price APIs differ on whether they return a market spot price or the local retail price by purity. Goldprice.dev gives live and historical spot prices for gold, silver and copper with cited sources, while KmalServico and AlQANAAS Gold Data quote per-gram or per-karat retail prices by country with no key. The National Bank of Poland publishes official gold prices with history.
