Know what changed, by how much, and when. Instantly.
Whether you're tracking gold, crude oil, or coffee beans, this API gives you accurate results. The Commodity Fluctuation API shows how prices moved over any time period—so you can tell the story behind the numbers. Just enter a date range and symbol. You'll get back the opening price, closing price, total change, and percent change.
Just pass in the commodity symbol (like XAU for gold) and a start/end date. You'll get back the opening and closing prices, the exact price change, and the percentage movement over that range.
From agricultural goods to energy, metals to rare materials—use the same endpoint across every symbol. One consistent format. All sectors covered.
Pair the commodity fluctuation API with the time series API to show detailed daily movement, then use this endpoint to show summarized change over the full range.
