Retrieving Historical Prices for Aluminum

To retrieve historical prices for Aluminum (XAL) using the Metals-API, developers can utilize the Historical Rates Endpoint. This endpoint allows users to specify a date and receive the corresponding price data. For example, a request for the historical price on October 20, 2025, would return a JSON response containing the price of Aluminum on that date.

{
    "success": true,
    "timestamp": 1760940033,
    "base": "USD",
    "date": "2025-10-20",
    "rates": {
        "XAL": 0.434783
    },
    "unit": "per troy ounce"
}

In this example, the response indicates that the price of Aluminum on October 20, 2025, was 0.434783 per troy ounce. Understanding how to interpret these responses is crucial for developers looking to integrate this data into their applications.

Understanding API Responses

The JSON response from the Metals-API is structured to provide clarity and ease of use. Each response includes several key fields:

success: A boolean value indicating whether the API request was successful.
timestamp: The time at which the data was retrieved, useful for ensuring data freshness.
base: The base currency against which the rates are provided, typically USD.
date: The specific date for which the historical price is being queried.
rates: An object containing the metal symbols and their corresponding prices.
unit: The unit of measurement for the prices, typically per troy ounce.

By understanding these fields, developers can effectively parse the data and utilize it within their applications. For instance, if a developer is building a dashboard to track metal prices, they can easily extract the price of Aluminum from the response and display it in real-time.

Common Use Cases for Metals-API

The Metals-API can be utilized in various applications, including:

Financial Applications: Developers can create applications that provide users with real-time pricing information for metals, enabling informed trading decisions.
