Fetching Data with Indices-API

To begin fetching data using the Indices-API, developers must first obtain an API key. This key is essential for authenticating requests and ensuring secure access to the API's features. Once you have your API key, you can start making requests to various endpoints.

Latest Rates Endpoint

The Latest Rates Endpoint allows you to get real-time exchange rates for all available indices. Here’s how you can use it:

{
"success": true,
"timestamp": 1772845314,
"base": "USD",
"date": "2026-03-07",
"rates": {
"SGD": 1.35,
"DOW": 0.00029,
"NASDAQ": 0.00039,
"S&P 500": 0.00024
},
"unit": "per index"
}

This response indicates that the exchange rate for SGD is 1.35 against USD, along with rates for other indices. Developers can utilize this data to monitor real-time market conditions.

Historical Rates Endpoint

To access historical exchange rates, you can use the Historical Rates Endpoint. This is particularly useful for analyzing trends over time:

{
"success": true,
"timestamp": 1772758914,
"base": "USD",
"date": "2026-03-06",
"rates": {
"SGD": 1.34,
"DOW": 0.00028,
"NASDAQ": 0.00038,
"S&P 500": 0.00023
},
"unit": "per index"
}

This response shows the historical rate for SGD on a specific date, allowing developers to analyze how the currency has performed over time.

Time-Series Endpoint

The Time-Series Endpoint is invaluable for predictive analytics, as it allows users to query exchange rates for a specific time period:

{
"success": true,
"timeseries": true,
"start_date": "2026-02-28",
"end_date": "2026-03-07",
"base": "USD",
"rates": {
"2026-02-28": {
"SGD": 1.33,
"DOW": 0.00028
},
"2026-03-01": {
"SGD": 1.34,
"DOW": 0.00029
},
"2026-03-07": {
"SGD": 1.35,
"DOW": 0.00029
}
},
"unit": "per index"
}

This response provides daily rates for SGD over a specified period, enabling developers to perform time-series analysis and build predictive models based on historical trends.

Fluctuation Endpoint

The Fluctuation Endpoint allows developers to track rate fluctuations between two dates:

"base": "USD",
"rates": {
"SGD": {
"start_rate": 1.33,
"end_rate": 1.35,
"change": 0.02,
"change_pct": 1.5
