Getting Started with Metals-API

To begin using the Metals-API, you first need to sign up on the Metals-API Website and obtain your API key. This key is essential for authenticating your requests. Once you have your key, you can start making requests to the various endpoints.

Retrieving Historical Prices for Gold (XAU)

To retrieve historical prices for Gold, you will primarily use the Historical Rates Endpoint. This endpoint allows you to specify a date and receive the price of Gold on that date. For example, if you want to find out the price of Gold on June 25, 2026, you would format your request as follows:

GET https://metals-api.com/api/historical/XAU?access_key=YOUR_API_KEY&date=2026-06-25

The response will include the price of Gold in USD per troy ounce, along with a success status and the date of the data. Here’s an example response:

{
"success": true,
"timestamp": 1782346683,
"base": "USD",
"date": "2026-06-25",
"rates": {
"XAU": 0.000485
},
"unit": "per troy ounce"
}

In this response, the "rates" field contains the price of Gold, which is crucial for historical analysis. By collecting this data over time, you can identify trends and make predictions about future price movements.

Utilizing the Time-Series Endpoint

The Time-Series Endpoint is another powerful feature that allows you to analyze price movements over a specified period. For instance, if you want to analyze Gold prices from June 19, 2026, to June 26, 2026, you would make a request like this:

GET https://metals-api.com/api/timeseries/XAU?access_key=YOUR_API_KEY&start_date=2026-06-19&end_date=2026-06-26

The response will provide daily prices for Gold during that period, allowing you to visualize trends and fluctuations. Here’s an example response:

{
"success": true,
"timeseries": true,
"start_date": "2026-06-19",
"end_date": "2026-06-26",
"base": "USD",
"rates": {
"2026-06-19": {
"XAU": 0.000485
},
"2026-06-21": {
"XAU": 0.000483
},
"2026-06-26": {
"XAU": 0.000482
}
},
"unit": "per troy ounce"
}

This data can be invaluable for traders looking to identify patterns or make predictions based on historical performance.

Analyzing Fluctuations

The Fluctuation Endpoint allows you to track how Gold prices change over time. By specifying a start and end date, you can see the percentage change in price, which is essential for understanding market volatility. For example:

GET https://metals-api.com/api/fluctuation/XAU?access_key=YOUR_API_KEY&start_date=2026-06-19&end_date=2026-06-26

The response will include the starting and ending rates, as well as the change in price and percentage change. Here’s an example response:

"fluctuation": true,
"start_date": "2026-06-19",
"end_date": "2026-06-26",
"base": "USD",
"rates": {
"XAU": {
"start_rate": 0.000485,
"end_rate": 0.000482,
"change": -3.0e-6,

}
},
"unit": "per troy ounce"
}

This information can help traders make informed decisions about when to buy or sell based on market conditions.

Open/High/Low/Close (OHLC) Data

For traders who rely on technical analysis, the Open/High/Low/Close (OHLC) Price Endpoint is crucial. This endpoint provides detailed information about the price movements of Gold over a specific time period. To access this data, you would use a request like:
