GET https://api.indices-api.com/open-high-low-close/{Index}/YYYY-MM-DD?access_key=YOUR_API_KEY

Replace {Index} with the desired index symbol (e.g., DOW, NASDAQ) and YYYY-MM-DD with the specific date you are interested in.

Sample Response

Upon making a successful request, you will receive a JSON response containing the OHLC data for the specified index. Here’s an example of what the response might look like:
