Commodity prices API for gold and oil

What the metals codes actually are

Coverage

Gold, silver, platinum and palladium per troy ounce; copper, aluminum, nickel, lead and tin per pound; iron ore per metric ton; plus daily gold and silver benchmark fix codes in USD, GBP and EUR.

Source

Aggregated from published market sources and normalized into one schema. We are not a party to any exchange or price-reporting agency.

Cadence

Latest available values carry a timestamp. Refresh cadence varies by source, market hours, dataset and plan; the daily fix codes publish once per trading day.

First endpoint

GET /v1/prices/latest?by_code=GOLD_USD

First call: gold and crude, same shape

Two requests, one header, one parser. The only difference between a metals call and an oil call is the by_code value.

• Responses are abridged for readability and show real observations captured on 2026-08-21; yours will differ.
• Add format=csv to either request for a flat CSV export instead of JSON.
• Read the unit field before doing arithmetic — gold is per troy ounce, Brent is per barrel.
