   Use the fields parameter to specify a comma-separated list of place data types to return. For example: `fields=formatted_address,name,geometry`. Use a forward slash when specifying compound values. For example: `opening_hours/open_now`.
 
-  Fields are divided into three billing categories: Basic, Contact, and Atmosphere. Basic fields are billed at base rate, and incur no additional charges. Contact and Atmosphere fields are billed at a higher rate. See the [pricing sheet](https://cloud.google.com/maps-platform/pricing/sheet/) for more information. Attributions, `html_attributions`, are always returned with every call, regardless of whether the field has been requested.
