freeTier property
Free tier value displayed in the Developers Console for this limit.
The free tier is the number of tokens that will be subtracted from the billed amount when billing is enabled. This field can only be set on a limit with duration "1d", in a billable group; it is invalid on any other limit. If this field is not set, it defaults to 0, indicating that there is no free tier for this service. Used by group-based quotas only.
