Retrieving Gold Historical Prices

To retrieve historical prices for Gold (XAU) using the Metals-API, you will primarily utilize the Historical Rates Endpoint. This endpoint allows you to specify a date and receive the corresponding price data. Here’s how to effectively use 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&symbols=XAU

In this URL:

access_key: Your unique API key for authentication.
date: The specific date for which you want to retrieve the historical price.
symbols: The metal symbol you are interested in, which in this case is XAU for Gold.

Example Request

For example, if you want to get the historical price of Gold on June 30, 2026, your request would look like this:

https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=2026-06-30&symbols=XAU

Example Response

The API will return a JSON response that includes the requested data. Here’s an example of what the response might look like:

{
"success": true,
"timestamp": 1782727653,
"base": "USD",
"date": "2026-06-30",
"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, which is USD in this case.
date: The date for which the price is provided.
rates: An object containing the price of Gold (XAU) for the specified date.
unit: The unit of measurement, which is per troy ounce.

Advanced Techniques for Data Retrieval

While the Historical Rates Endpoint is straightforward, there are advanced techniques that can enhance your data retrieval process. For instance, you can combine the Historical Rates Endpoint with the Time-Series Endpoint to analyze trends over a specific period.

Using the Time-Series Endpoint

The Time-Series Endpoint allows you to retrieve daily historical rates between two dates. This is particularly useful for analyzing price movements over time. 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&symbols=XAU

For example, to get Gold prices from June 23, 2026, to June 30, 2026, your request would be:

https://metals-api.com/api/timeseries?access_key=YOUR_API_KEY&start_date=2026-06-23&end_date=2026-06-30&symbols=XAU

Example Response for Time-Series

The response for this request would include daily prices for Gold over the specified period:

{
"success": true,
"timeseries": true,
"start_date": "2026-06-23",
"end_date": "2026-06-30",
"base": "USD",
"rates": {
"2026-06-23": {
"XAU": 0.000485
},
"2026-06-25": {
"XAU": 0.000483
},
"2026-06-30": {
