The cost to access ArcGIS location services depends on the type of ArcGIS account you have and the service operation you use.
-
If you have an ArcGIS Developer account, you are billed in US dollars. To determine the cost of accessing different services, go to Pricing. A free tier of access is available for some services.
-
If you have an ArcGIS Online account, you are billed in credits. To determine the cost of accessing different services, go to Understanding credits.
If you have ArcGIS Enterprise, there is no cost for accessing your own ArcGIS services.
To learn about accounts, content and data, and basemap layer attribution, go to Deployment in the Mapping APIs and locaiton services guide.
