Latest Rates Query

To get the latest rates for the NASDAQ Composite Index, you can use the Latest Rates Endpoint. Here’s an example response:

{
"success": true,
"timestamp": 1758448949,
"base": "USD",
"date": "2025-09-21",
"rates": {
"DOW": 0.00029,
"NASDAQ": 0.00039,
"S&P 500": 0.00024,
"FTSE 100": 0.00058,
"DAX": 0.00448,
"CAC 40": 0.00137,
"NIKKEI 225": 0.0125
},
"unit": "per index"
}

In this response, the "rates" object provides the latest exchange rates for various indices, including the NASDAQ. By monitoring these rates over time, traders can identify sudden changes that may indicate volatility spikes.

Historical Rates Query

Accessing historical rates can provide context for current market conditions. Here’s an example response from the Historical Rates Endpoint:

{
"success": true,
"timestamp": 1758362549,

By comparing historical rates with current rates, traders can identify trends and potential volatility spikes. For instance, if the NASDAQ's rate has significantly increased compared to previous days, it may indicate a bullish trend or a potential market correction.

Fluctuation Query

The Fluctuation Endpoint is particularly useful for detecting volatility spikes. Here’s an example response:

{
"success": true,
"fluctuation": true,
"start_date": "2025-09-14",
"end_date": "2025-09-21",
"base": "USD",
"rates": {
"DOW": {
"start_rate": 0.00028,
"end_rate": 0.00029,
"change": 1.0e-5,
