Getting Started with Historical Rates

To retrieve historical prices for Gold (XAU), you will primarily use the Historical Rates Endpoint. This endpoint allows you to access historical exchange rates for any date since 1999. The process is straightforward and involves making a simple API request.

Endpoint Structure

The basic structure for accessing historical rates is as follows:

https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=YYYY-MM-DD&base=XAU

In this URL:

YOUR_API_KEY: Replace this with your actual API key.
YYYY-MM-DD: Specify the date for which you want to retrieve historical data.
XAU: This is the base currency for Gold.

Example Request

For example, if you want to get the historical price of Gold on August 19, 2026, your request would look like this:

https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=2026-08-19&base=XAU

Understanding the API Response

The response from the API will be in JSON format, providing you with the necessary data. Here’s an example of what the response might look like:

{
"success": true,
"timestamp": 1787155642,
"base": "USD",
"date": "2026-08-19",
"rates": {
"XAU": 0.000485,
"XAG": 0.03825,
"XPT": 0.000915,
"XPD": 0.000748
},
"unit": "per troy ounce"
}

In this response:

success: Indicates whether the request was successful.
timestamp: The time at which the data was retrieved.
base: The base currency for the rates.
date: The date for which the rates are provided.
rates: An object containing the rates for various metals, including Gold (XAU).

Advanced Use Cases

Beyond simply retrieving historical rates, the Metals-API offers advanced functionalities that can enhance your applications. For instance, you can use the Time-Series Endpoint to analyze trends over a specific period. This is particularly useful for financial analysts and developers looking to build applications that require historical data analysis.

Time-Series Endpoint

The Time-Series Endpoint allows you to query exchange rates for a specific time period. The structure for this endpoint is as follows:

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

For example, to get Gold prices from August 13, 2026, to August 20, 2026, your request would be:

https://metals-api.com/api/timeseries?access_key=YOUR_API_KEY&start_date=2026-08-13&end_date=2026-08-20&base=XAU

Example Response for Time-Series

The response for the Time-Series request will provide daily rates for the specified period:

{
"success": true,
"timeseries": true,
"start_date": "2026-08-13",
"end_date": "2026-08-20",
"base": "USD",
"rates": {
"2026-08-13": {
"XAU": 0.000485,
"XAG": 0.03825,
"XPT": 0.000915
},
"2026-08-15": {
"XAU": 0.000483,
"XAG": 0.0382,
"XPT": 0.000913
},
"2026-08-20": {
"XAU": 0.000482,
"XAG": 0.03815,
"XPT": 0.000912
}
},
"unit": "per troy ounce"
}

This response provides a comprehensive view of how Gold prices have changed over the specified period, allowing for in-depth analysis and insights.

Common Pitfalls and Troubleshooting

When working with the Metals-API, developers may encounter common issues. Here are some troubleshooting tips:

Invalid API Key: Ensure that your API key is correct and has not expired.
