Key Features and Endpoints

The Indices-API provides several key endpoints that developers can utilize to extract valuable data:

Latest Rates Endpoint

This endpoint delivers real-time exchange rates for all available indices. Depending on the subscription plan, users can receive updates every 60 minutes or even more frequently. For example, a typical response from this endpoint might look like:

{
"success": true,
"timestamp": 1768179189,
"base": "USD",
"date": "2026-01-12",
"rates": {
"DOW": 0.00029,
"NASDAQ": 0.00039,
"S&P 500": 0.00024,

"DAX": 0.00448,
"CAC 40": 0.00137,
"NIKKEI 225": 0.0125
},
"unit": "per index"
}

In this response, the "rates" object provides the current value of each index relative to USD, allowing developers to quickly assess market conditions.

Historical Rates Endpoint

Accessing historical exchange rates is essential for trend analysis. The Historical Rates Endpoint allows users to query data for any date since 1999. A sample response might be:
