Fetching Historical Prices for Dysprosium

To fetch historical prices for Dysprosium using the Metals-API, you will need to utilize the Historical Rates Endpoint. This endpoint allows you to specify a date and retrieve the corresponding price data. Here’s how you can do it:

{
    "success": true,
    "timestamp": 1749279616,
    "base": "USD",
    "date": "2025-06-07",
    "rates": {
        "DYS": 0.000485
    },
    "unit": "per troy ounce"
}

In this example response, the API indicates a successful request, providing the historical price of Dysprosium for the specified date. The response includes the base currency (USD), the date of the price, and the rate for Dysprosium.

Understanding API Responses

When working with the Metals-API, it is essential to understand the structure of the API responses. Each response typically includes the following fields:

• success: A boolean indicating whether the API request was successful.
• timestamp: The server timestamp indicating when the request was processed.
• base: The base currency for the exchange rates provided.
• date: The date for which the historical price is being requested.
• rates: An object containing the metal symbols and their corresponding prices.
• unit: The unit of measurement for the prices (e.g., per troy ounce).

Understanding these fields will help you effectively parse and utilize the data returned by the API in your applications.

Practical Use Cases

The Metals-API can be integrated into various applications and platforms, providing valuable insights and functionalities. Here are some practical use cases for fetching historical prices of Dysprosium:
