`num`	Number of values to be returns, to be used in conjunction with the `end_date` parameter to return the n-values from an end point. The EIA API will only accept the `num` parameter in conjunction with the `end_date` parameter and not `start_date`. If `num` is supplied, the `start_date` argument will be ignored.
`start_date`	Optional start date filter—if supplied, returns data after the specified start date. Argument accepts valid numeric, character, date or datetime format object. If numeric it must be in %Y form (i.e. four digit year). If character string, it must be in year-month-date (%Y-%m-%d) format.
