Understanding the OHLC Endpoint

The OHLC endpoint is a critical feature for traders who need to analyze price movements. By querying the Indices-API with the appropriate parameters, you can obtain the open, high, low, and close prices for the S&P 500 or any other index. This data is essential for technical analysis, allowing traders to identify trends and make informed decisions.

Sample Request

To retrieve OHLC data for the S&P 500, you would make a request to the following endpoint:

https://api.indices-api.com/open-high-low-close/S&P500/YYYY-MM-DD

In this request, replace YYYY-MM-DD with the desired date for which you want to retrieve the OHLC data.

Sample Response

Here is an example of a successful response from the OHLC endpoint:

{
"success": true,
"timestamp": 1762907268,
"base": "USD",
"date": "2025-11-12",
"rates": {
"S&P 500": {
"open": 0.0124,
"high": 0.0126,
"low": 0.0123,
"close": 0.0125
}
},
"unit": "per index"
}

In this response, the fields represent the following:
