{
    "success": true,
    "timestamp": 1763190053,
    "base": "USD",
    "date": "2025-11-15",
    "rates": {
        "XCU": 0.294118
    },
    "unit": "per troy ounce"
}

In this example, the response indicates that the price of Copper (XCU) on November 15, 2025, was 0.294118 per troy ounce. This data can be invaluable for analysts looking to understand historical price movements and trends.

Using the Historical LME Endpoint

The Historical LME Endpoint provides access to historical rates specifically for LME symbols, including Copper. This endpoint is particularly useful for those interested in the London Metal Exchange prices, which are widely regarded as the global benchmark for metal pricing.

To use this endpoint, you would specify the LME symbol for Copper and the desired date range. The response will include detailed pricing information, allowing for in-depth analysis of market trends over time.
