}
},
"unit": "per index"
}

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

Response Handling and Automation Ideas

Handling API responses effectively is crucial for building robust applications. Each response from the Indices-API will include a success status, a timestamp, and the requested data. It's essential to check the success field before processing the data. For example:

if (response.success) {
// Process data
} else {
// Handle error
}

To automate the retrieval of daily DAX updates, consider setting up a cron job or a scheduled task that makes requests to the Latest Rates Endpoint at a specific time each day. This can help keep your investment analysis tool updated with the latest performance data.
