How to get historical data of currency(EX:USDINR Futures) via api for a specific interval

When we try to read historical data of USDINR futures for past 5 years we are getting wrong data via below API.
API: 9:00:00&to=2016-02-01
"status": "success",
"data": {
"candles": []

Note: We tried using continous flag to 1 but that gives only 1 day interval candles but not 1 min. Please suggest
