Example of Historical Rates Endpoint

When querying the Historical Rates Endpoint, the API response will include the following structure:

{
    "success": true,
    "timestamp": 1748584816,
    "base": "USD",
    "date": "2025-05-30",
    "rates": {
        "XCU": 0.294118
    },
    "unit": "per troy ounce"
}

In this example, the response indicates that the historical price of copper (XCU) on May 30, 2025, was 0.294118 per troy ounce. This data is crucial for analysts and traders who need to understand price movements over time.
