"base": "USD",
"date": "2026-01-24",
"rates": {
"CNY": 0.00015,
"EUR": 0.00012,
"JPY": 0.015
},
"unit": "per currency"
}

This response shows the latest exchange rates for the CNY against USD, EUR, and JPY. The "rates" field provides the current value of the CNY relative to these currencies.

Historical Rates Endpoint

{
"success": true,
"timestamp": 1769150945,

"rates": {
"CNY": 0.00014,
"EUR": 0.00011,
"JPY": 0.014
},
"unit": "per currency"
}

In this example, the historical rates endpoint returns the exchange rate for the CNY on a specific date, allowing users to analyze past performance.

Time-Series Endpoint

{
"success": true,
"timeseries": true,
"start_date": "2026-01-17",
"end_date": "2026-01-24",
"base": "USD",
"rates": {
"2026-01-17": {
"CNY": 0.00014
},
"2026-01-19": {
"CNY": 0.00015
},
"2026-01-24": {
"CNY": 0.00015
}
},
"unit": "per currency"
}

This response provides a time series of exchange rates for the CNY over a specified period, enabling users to visualize trends and fluctuations.

Convert Endpoint

{
"success": true,
"query": {
"from": "USD",
"to": "CNY",
"amount": 1000
},
"info": {
"timestamp": 1769237345,
"rate": 0.00015
},
"result": 0.15,
"unit": "per currency"
}

The convert endpoint allows users to convert a specified amount from one currency to another. In this case, it shows the conversion of 1000 USD to CNY.

Fluctuation Endpoint

{
"success": true,
"fluctuation": true,
"start_date": "2026-01-17",
"end_date": "2026-01-24",
"base": "USD",
"rates": {
"CNY": {
"start_rate": 0.00014,
"end_rate": 0.00015,
"change": 0.00001,
"change_pct": 7.14
}
},
"unit": "per currency"
}

This response illustrates how the CNY fluctuated between two dates, providing both the start and end rates, as well as the percentage change.

OHLC (Open/High/Low/Close) Endpoint

{
"success": true,
"timestamp": 1769237345,

Building the Interactive Dashboard with RapidMiner

Now that we have a solid understanding of the Indices-API and its capabilities, let's discuss how to build an interactive dashboard using RapidMiner. RapidMiner is a powerful data science platform that allows users to create visualizations and perform data analysis without extensive programming knowledge.

Step 1: Setting Up RapidMiner

To get started, download and install RapidMiner Studio from the official website. Once installed, create a new project and familiarize yourself with the interface. RapidMiner provides a user-friendly environment where you can drag and drop components to build your dashboard.

Step 2: Connecting to the Indices-API

To connect RapidMiner to the Indices-API, you will need to use the Web Mining extension. This extension allows you to make API calls directly from RapidMiner. Follow these steps:

  1. Install the Web Mining extension from the RapidMiner Marketplace.
  2. In your RapidMiner project, create a new process.
  3. Use the "Web Service" operator to configure the API call. Enter the base URL for the Indices-API and include your API key in the request.

Step 3: Fetching Data

Once you have configured the Web Service operator, you can specify which endpoint you want to call. For example, to get the latest rates for the CNY, set the endpoint to the latest rates URL. Make sure to handle the API response correctly by mapping the response fields to the appropriate attributes in RapidMiner.

Step 4: Data Transformation and Visualization

After fetching the data, you may need to perform some data transformation to prepare it for visualization. Use operators like "Select Attributes" to choose relevant fields and "Generate Attributes" to create new calculated fields if necessary. RapidMiner offers various visualization options, including line charts, bar charts, and tables, to display the CNY performance effectively.

Step 5: Creating Interactive Elements

To enhance user interaction, consider adding filters and sliders to your dashboard. RapidMiner allows you to create dynamic visualizations that update in real-time based on user input. This feature is particularly useful for analyzing how the CNY performs over different time periods or against various currencies.

Best Practices for Data Presentation

When building your interactive dashboard, keep the following best practices in mind:

  • Clarity: Ensure that your visualizations are easy to understand. Use clear labels, legends, and tooltips to provide context for the data.
  • Consistency: Maintain a consistent color scheme and layout throughout your dashboard to enhance usability.
  • Interactivity: Incorporate interactive elements that allow users to explore the data further, such as filtering options and drill-down capabilities.
  • Real-time Updates: If possible, configure your dashboard to refresh data at regular intervals to provide users with the most current information.

Conclusion

Building an interactive dashboard to visualize the performance of the Chinese Renminbi Yuan using the Indices-API and RapidMiner is a powerful way to gain insights into currency trends. By leveraging the capabilities of the Indices-API, developers can access real-time and historical data, enabling them to create comprehensive visualizations that inform decision-making. Remember to follow best practices for data presentation to ensure your dashboard is user-friendly and effective.
