Example Queries and Data Interpretation

To effectively utilize the Indices-API for detecting volatility spikes in the NZ50, developers can construct various queries to retrieve relevant data. Below are examples of how to use the API's endpoints and interpret the responses.

Latest Rates Endpoint

To retrieve the latest rates for the NZ50, a developer can use the following query:

GET https://api.indices-api.com/latest?access_key=YOUR_API_KEY&symbols=NZX50

The response might look like this:

{

"base": "NZD",
"date": "2025-08-12",
"rates": {
"NZX50": 12345.67
},
"unit": "per index"
}

In this response, the "rates" field indicates the current value of the NZ50, which is essential for assessing its performance at any given moment. Traders can use this data to determine whether the index is experiencing a volatility spike compared to historical values.

Historical Rates Endpoint

To analyze historical data for the NZ50, a developer can query the historical rates endpoint:

GET https://api.indices-api.com/historical?access_key=YOUR_API_KEY&symbols=NZX50&date=2025-08-11

The response may look like this:

{
"success": true,

By comparing the latest rate with historical rates, traders can identify significant changes that may indicate a volatility spike. For instance, if the latest rate is significantly higher than the historical rate, it may suggest increased market activity or sentiment.

Fluctuation Endpoint

To track fluctuations in the NZ50 over a specific period, a developer can use the fluctuation endpoint:

GET https://api.indices-api.com/fluctuation?access_key=YOUR_API_KEY&symbols=NZX50&start_date=2025-08-05&end_date=2025-08-12

The response might be structured as follows:

{
"success": true,
"fluctuation": true,
"start_date": "2025-08-05",
"end_date": "2025-08-12",
"base": "NZD",
"rates": {
