Accessing Historical Rates

To access historical rates for metals using the Metals-API, you will need to utilize the historical rates endpoint. This endpoint allows you to specify a date in the format YYYY-MM-DD to retrieve the exchange rates for that particular day. For example, if you want to get the historical rate for Gold (XAU) on March 10, 2026, you would structure your request as follows:

GET https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=2026-03-10&base=USD&symbols=XAU

The response will provide you with the exchange rate for Gold relative to USD on that specific date. Here’s an example of what the JSON response might look like:

{
"success": true,
"timestamp": 1773104895,
"base": "USD",
"date": "2026-03-10",
"rates": {
"XAU": 0.000485
},
"unit": "per troy ounce"
}

In this response, the "success" field indicates that the request was successful, while the "rates" object contains the exchange rate for Gold (XAU) on the specified date.

Time-Series Data

For developers looking to analyze trends over a specific period, the time-series endpoint is invaluable. This endpoint allows you to specify a start date and an end date to retrieve daily historical rates for the metals of your choice. For instance, if you want to analyze Gold (XAU) rates from March 4, 2026, to March 11, 2026, your request would look like this:

GET https://metals-api.com/api/timeseries?access_key=YOUR_API_KEY&start_date=2026-03-04&end_date=2026-03-11&base=USD&symbols=XAU

The response will provide a detailed breakdown of the daily rates for the specified period:

{
"success": true,
"timeseries": true,
"start_date": "2026-03-04",
"end_date": "2026-03-11",
"base": "USD",
"rates": {
"2026-03-04": {
"XAU": 0.000485
},
"2026-03-05": {
"XAU": 0.000483
},
"2026-03-06": {
"XAU": 0.000482
},
"2026-03-11": {
"XAU": 0.000482
}
},
