Accessing Real-Time Aluminum Prices

To access real-time aluminum prices using the Metals-API, follow these steps:

Step 1: Obtain Your API Key

First, you need to sign up for an account on the Metals-API website. Once registered, you will receive an API key that you will use to authenticate your requests. This key is essential for accessing the API's features securely.

Step 2: Make Your First API Call

To retrieve the latest aluminum prices, you will use the Latest Rates Endpoint. The basic structure of the API call is as follows:

GET https://metals-api.com/api/latest?access_key=YOUR_API_KEY&base=USD&symbols=XAL

Replace YOUR_API_KEY with your actual API key. This request will return the latest aluminum price in USD.

Step 3: Understanding the API Response

The response from the API will be in JSON format and will look something like this:

{
"success": true,
"timestamp": 1787703608,
"base": "USD",
"date": "2026-08-26",
"rates": {
"XAL": 0.434783
},
"unit": "per troy ounce"
}

In this response:

• success: Indicates whether the API call was successful.
• timestamp: The time at which the data was retrieved.
• base: The base currency used for the exchange rate (USD in this case).
• date: The date of the data retrieved.
• rates: An object containing the exchange rates for the requested symbols, including aluminum (XAL).
• unit: The unit of measurement for the price (per troy ounce).

Step 4: Exploring Historical Data

To access historical aluminum prices, you can use the Historical Rates Endpoint. The API call structure is as follows:

GET https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=YYYY-MM-DD&symbols=XAL

Replace YYYY-MM-DD with the desired date. The response will provide the aluminum price for that specific date, allowing you to analyze historical trends.

Step 5: Utilizing the Time-Series Endpoint

If you want to analyze price movements over a specific period, the Time-Series Endpoint is invaluable. The API call structure is:

GET https://metals-api.com/api/timeseries?access_key=YOUR_API_KEY&start_date=YYYY-MM-DD&end_date=YYYY-MM-DD&base=USD&symbols=XAL

This will return daily prices for aluminum between the specified start and end dates, enabling detailed trend analysis.
