Integrating the Indices-API into Your Dashboard

To build an interactive dashboard, you will need to follow several integration steps. Below is a comprehensive guide to help you get started:

Step 1: Obtain Your API Key

First, sign up for an account on the Indices-API website. Once registered, you will receive an API key that you will use to authenticate your requests. This key must be included in the access_key parameter of your API calls.

Step 2: Set Up Your Development Environment

Choose a development environment that you are comfortable with. You can use JavaScript, Python, or any other language that supports HTTP requests. For this example, we will focus on JavaScript, as it is commonly used for web applications.

Step 3: Making API Calls

Use the following examples to understand how to make API calls to the Indices-API:

Latest Rates Endpoint

To get the latest exchange rates, make a GET request to the following URL:

https://api.indices-api.com/v1/latest?access_key=YOUR_API_KEY

The response will look like this:

{
"success": true,
"timestamp": 1771253403,
"base": "USD",
"date": "2026-02-16",
"rates": {
"TRY": 0.00012,
"EUR": 0.00024,
"USD": 1.0
},
"unit": "per currency"
}

Historical Rates Endpoint

To access historical rates, append a date to your request:

https://api.indices-api.com/v1/historical?access_key=YOUR_API_KEY&date=2026-02-15

Example response:

{
"success": true,
"timestamp": 1771167003,
"base": "USD",
"date": "2026-02-15",
"rates": {
"TRY": 0.00011,
"EUR": 0.00023,
"USD": 1.0
},
"unit": "per currency"
}

Time-Series Endpoint

To get exchange rates for a specific time period, use the time-series endpoint:

https://api.indices-api.com/v1/timeseries?access_key=YOUR_API_KEY&start_date=2026-02-09&end_date=2026-02-16

Response example:

{
"success": true,
"timeseries": true,
"start_date": "2026-02-09",
"end_date": "2026-02-16",
"base": "USD",
"rates": {
"2026-02-09": {"TRY": 0.00011},
"2026-02-10": {"TRY": 0.00012},
"2026-02-11": {"TRY": 0.00013}
},
"unit": "per currency"
}

Step 4: Visualizing Data with Google Maps API

Once you have the data, the next step is to visualize it. The Google Maps API allows you to create interactive maps that can display currency performance geographically. You can use markers to represent different currencies and their performance relative to the Turkish Lira.

Step 5: Best Practices for Data Presentation

When presenting data, consider the following best practices:

• Use clear labels and legends to ensure users understand the data being presented.
• Incorporate interactive elements such as tooltips and clickable markers for enhanced user engagement.
• Ensure that your dashboard is responsive and works well on various devices.
• Regularly update the data to reflect real-time changes in currency performance.
