  characters number
  
  Restricts the number of total characters (across text translation, document translation, and text improvement) that can be consumed by an API key in a one-month usage period. Setting the limit to 0 means the API key will not be able to consume characters. Setting the limit to null disables the limit, effectively allowing unlimited usage.
