Retrieving Historical Prices for Gold (XAU)

To retrieve historical prices for Gold (XAU) using the Metals-API, you will primarily use the Historical Rates Endpoint. This endpoint allows you to access historical exchange rates for any date since 1999. Here’s how to effectively utilize this endpoint:

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=USD&symbols=XAU

In this URL:

access_key: Your unique API key, which you can obtain upon registration.
date: The specific date for which you want to retrieve historical prices, formatted as YYYY-MM-DD.
base: The base currency for the exchange rate, typically set to USD.
symbols: The metal symbol you wish to query, in this case, XAU for Gold.

Example Request

For instance, if you want to retrieve the historical price of Gold on May 10, 2026, your request would look like this:

https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=2026-05-10&base=USD&symbols=XAU

Example Response

The API will return a JSON response containing the historical price data. Here’s an example of what the response might look like:

{
"success": true,
"timestamp": 1778353689,
"base": "USD",
"date": "2026-05-10",
"rates": {
"XAU": 0.000482
},
"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 used for the exchange rate.
date: The date for which the historical price is provided.
rates: An object containing the metal symbol and its corresponding price.
unit: The unit of measurement for the price, typically per troy ounce.

Advanced Techniques for Data Retrieval

While the basic retrieval of historical prices is straightforward, developers can enhance their applications by utilizing additional features of the Metals-API. Here are some advanced techniques:

Using the Time-Series Endpoint

The Time-Series Endpoint allows you to retrieve exchange rates for a specific period, which can be particularly useful for trend analysis. 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=USD&symbols=XAU

For example, to get the historical prices of Gold from May 3, 2026, to May 10, 2026, your request would be:

https://metals-api.com/api/timeseries?access_key=YOUR_API_KEY&start_date=2026-05-03&end_date=2026-05-10&base=USD&symbols=XAU

Example Response for Time-Series

The response will include daily rates for the specified period:

{
"success": true,
"timeseries": true,
"start_date": "2026-05-03",
"end_date": "2026-05-10",
"base": "USD",
"rates": {
"2026-05-03": {
"XAU": 0.000485
},
"2026-05-05": {
"XAU": 0.000483
},
"2026-05-10": {
"XAU": 0.000482
}
},
"unit": "per troy ounce"
}

This response provides a clear view of how Gold prices have changed over the specified period, allowing for deeper analysis and insights.
