To retrieve historical intraday price data for more than 1 month, you will need to implement a loop that iterates over day intervals covering the entire desired time range. This approach ensures a suitable response speed for the data being returned. For example, if you require more than 1 month of 30-minute data, you can make queries over day intervals to cover the entire desired time range.
