Get a List of Car Model Years for a Specific Car Make/Model: You can get the entire list of car model years or use some basic filters to return the array of car model years you’re interested in for a specific car make/model.
Get Details on a Specific Car Make/Model/Year: Returns relevant information for a specific car make/model/year, including the car styles and trims. The information can also be narrowed down with filters.
Get Total Count of Model Years for a Car Make/Model: Get the total number of model years of a specific car make/model. You can use filters to get subtotals (e.g. give me the total number of used 1999 model years for a car make/model).
These three endpoints provide all the necessary data points.
