The structure of this data is different depending on if a search_result_id was supplied to the API. Please read below for more details.

As you can see above, this API accepts an optional search_result_id parameter. We will refer to this API with no search_result_id as Regular Mode and this API with an included search_result_id as Search Mode.

It is very important to realize that the exits responses returned from Regular Mode are quite different in structure than Search Mode. The data for highway_in_state, previous_highway_in_state, and next_highway_in_state are the same regardless of which mode you are in, but exits will be different.
