Do I have to use an API key when using Distance Matrix API?
Google Documentation states that the key should be included in every request, but I see I can get the duration and distance values without including a key.
https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=Washington,DC&destinations=New+York+City,NY
But I do need to use a key when I need the duration_in_traffic
variable.
https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=Washington,DC&destinations=New+York+City,NY&departure_time=1531583990&key=API_KEY
These are the price stated by Google for basic and advanced, https://developers.google.com/maps/documentation/distance-matrix/usage-and-billing#distance-matrix
And I am wondering if I should use my API key or not when sending basic requests as I will have to pay if I use an API Key.
