Accessing Historical Prices for Gold

To retrieve historical prices for Gold using the Metals-API, you will primarily utilize the Historical Rates Endpoint. This endpoint allows you to query historical prices for any date since 2019, making it an invaluable resource for analysis.

Using the Historical Rates Endpoint

The Historical Rates Endpoint can be accessed by appending a date in the format YYYY-MM-DD to the base URL. For example, to retrieve the historical price of Gold on April 18, 2026, your request would look like this:

https://metals-api.com/api/historical/XAU?access_key=YOUR_API_KEY&date=2026-04-18

The response will include the price of Gold in relation to USD, along with a timestamp and the base currency. Here’s an example of a typical response:

{
"success": true,
"timestamp": 1776471266,
"base": "USD",
"date": "2026-04-18",
"rates": {
"XAU": 0.000485
},
"unit": "per troy ounce"
}

In this response, the "rates" field provides the price of Gold (XAU) per troy ounce, which is essential for any analysis or reporting.

Understanding the Response Fields

Each response from the Metals-API contains several key fields:

• success: Indicates whether the request was successful.

• unit: The unit of measurement for the price (e.g., per troy ounce).

Advanced Techniques for Data Analysis

Once you have access to historical prices, you can employ various data analysis techniques to extract meaningful insights. For instance, you can use time-series analysis to identify trends and patterns in Gold prices over time.

Time-Series Analysis

The Time-Series Endpoint allows you to query daily historical rates between two dates, providing a comprehensive view of price movements. This is particularly useful for identifying trends and making predictions based on historical data.

To use the Time-Series Endpoint, you would structure your request as follows:

https://metals-api.com/api/timeseries/XAU?access_key=YOUR_API_KEY&start_date=2026-04-12&end_date=2026-04-19

The response will include daily rates for Gold within the specified date range, enabling you to analyze fluctuations and trends effectively.

Example Response for Time-Series Endpoint

Here’s an example of a response from the Time-Series Endpoint:

{
"success": true,
"timeseries": true,
"start_date": "2026-04-12",
"end_date": "2026-04-19",
"base": "USD",
"rates": {
"2026-04-12": {
"XAU": 0.000485
},
"2026-04-14": {
"XAU": 0.000483
