About Metal Sentinel
Metal Sentinel is a REST API providing current and historical pricing data for ten spot-traded metals: gold, silver, platinum, palladium, rhodium, copper, nickel, aluminum, lead, and zinc, sourced from Kitco. Gold prices are additionally available karat-priced in 24k, 18k, 14k, and 9k. The API also offers mining and commodity stock data, cryptocurrency quotes, and foreign exchange rates, with pricing available in multiple fiat currencies and crypto tokens.
Endpoints cover spot prices, historical daily data, point-in-time snapshots at 30-day, 60-day, 1-year and 5-year intervals, and reference data such as market open/close status and lists of supported metals, currencies, and cryptocurrencies. The API is distributed through RapidAPI and includes a free tier (15,000 requests/month, 60 requests per minute) alongside paid Pro, Ultra, and Mega tiers with higher request limits. A free WordPress plugin and embeddable price widgets are also available for users who do not want to write code.
The product is aimed at developers building fintech applications, e-commerce jewelry storefronts, and commodities trading dashboards that require real-time or historical metals pricing data.
