Accessing Historical Prices for CNY

To retrieve historical prices for the Chinese Renminbi Yuan (CNY), you will primarily use the Historical Rates Endpoint. Here’s how to do it step-by-step:

Step 1: Make a Request to the Historical Rates Endpoint

To access historical rates, you will need to format your request URL as follows:

https://metals-api.com/api/historical?access_key=YOUR_API_KEY&date=YYYY-MM-DD&base=CNY

Replace YOUR_API_KEY with your actual API key and YYYY-MM-DD with the date for which you want to retrieve the historical price.

Step 2: Understanding the API Response

The response from the Historical Rates Endpoint will include several key fields:

• success: A boolean indicating whether the request was successful.
• timestamp: The time at which the data was retrieved.
• base: The base currency for the exchange rate (in this case, CNY).
• date: The date for which the historical rate is provided.
• rates: An object containing the exchange rates for various currencies against CNY.

Here is an example response:

{
"success": true,
"timestamp": 1785716098,
"base": "CNY",
"date": "2026-08-03",
"rates": {
"USD": 0.154,
"EUR": 0.130,
"JPY": 16.50
}
}

In this example, the response indicates that the request was successful, and it provides the exchange rates for USD, EUR, and JPY against CNY for the specified date.

Step 3: Analyzing Historical Data

Once you have retrieved the historical rates, you can analyze the data to identify trends, patterns, and fluctuations in the value of CNY. This analysis can be beneficial for financial forecasting, investment strategies, and market research.

Advanced Techniques for Using Metals-API

Beyond simply retrieving historical prices, the Metals-API offers advanced features that can enhance your data analysis capabilities:

Using the Time-Series Endpoint

The Time-Series Endpoint allows you to obtain exchange rates for a specific period. To use this endpoint, format your request as follows:

https://metals-api.com/api/timeseries?access_key=YOUR_API_KEY&start_date=YYYY-MM-DD&end_date=YYYY-MM-DD&base=CNY

This will return a series of exchange rates for the specified date range, enabling you to perform in-depth analysis over time.

Implementing the Fluctuation Endpoint

The Fluctuation Endpoint can help you track the changes in CNY's value over a specified period. This is particularly useful for traders looking to capitalize on market movements. Your request would look like this:

https://metals-api.com/api/fluctuation?access_key=YOUR_API_KEY&start_date=YYYY-MM-DD&end_date=YYYY-MM-DD&base=CNY

The response will provide details on the starting and ending rates, as well as the percentage change, giving you a clear picture of market dynamics.
