Key Features and Endpoints

The Indices-API offers several key features that are particularly useful for detecting volatility spikes in the VXTH. Below are some of the most relevant endpoints and their functionalities:

Latest Rates Endpoint

The Latest Rates endpoint provides real-time exchange rate data for various indices, including the VXTH. Depending on your subscription plan, this data can be updated every 60 minutes or even more frequently. For example, a typical response from this endpoint might look like this:

{
"success": true,
"timestamp": 1768093148,
"base": "USD",
"date": "2026-01-11",
"rates": {
"VXTH": 0.00029,
"DOW": 0.00029,
"NASDAQ": 0.00039,
"S&P 500": 0.00024
},
"unit": "per index"
}

This response indicates the current value of the VXTH relative to USD, allowing traders to monitor real-time fluctuations.

Historical Rates Endpoint

The Historical Rates endpoint allows users to access past exchange rates for any date since 1999. This is particularly useful for analyzing how the VXTH has reacted to historical market events. A sample response might look like this:

{
"success": true,
"timestamp": 1768006748,
"base": "USD",
"date": "2026-01-10",

"unit": "per index"
}

By comparing historical data with current rates, traders can identify patterns and potential volatility spikes.

Fluctuation Endpoint

The Fluctuation endpoint is invaluable for tracking rate changes between two dates. This can help traders identify significant volatility spikes in the VXTH. An example response might be:

{

"start_date": "2026-01-04",
"end_date": "2026-01-11",
"base": "USD",
"rates": {
"VXTH": {
"start_rate": 0.00028,
"end_rate": 0.00029,
"change": 1.0e-5,
"change_pct": 3.57
}
},
"unit": "per index"
}

This response shows the change in the VXTH over a specified period, highlighting any significant fluctuations that may indicate increased market volatility.

OHLC (Open/High/Low/Close) Price Endpoint

The OHLC endpoint provides essential data for technical analysis, allowing traders to see the open, high, low, and close prices for the VXTH over a specific time period. A typical response might look like this:
