 # The API interface
 
 The package currently provides an interface to the [Quantec](https://www.easydata.co.za/) data API. The function `quantec_get_data` has the following options:
 
 * `time_series_code` time series code to return, `NMS-EC_BUS,NMS-GA_BUS`
 * `freq` frequency to return `M`, `Q` or `A`
-* `start_year` year to start
-* `end_year` year to end
-* `respformat` to return `csv` or `json`
+* `start_year` year to start (OPTIONAL)
+* `end_year` year to end (OPTIONAL)
 * `log_file` log file to output to
-* `is_tidy` tidyformat for easy read
