# getCreditUsageByType

What used the credits this billing period, per credit type: `series[].totalUnits` for AI_CREDITS, SMS_CREDITS (outbound text segments), CALLING_MINUTES, SKIPTRACE, EMAIL_VERIFICATION and EXPORT_PROPERTIES, the Billing page usage chart's own figures (each day's use, charges less that day's refunds, summed). Pass timeZone (getMyProfile.resolvedTimezone) so the days fall as the person's chart draws them; omitted, they are UTC days. A refund that lands a day after its charge is not netted, so a total can exceed getBillingSummary's `planUsage.usedThisPeriod`; quote this one as what used the credits, that one as what is left. Null before a first billing period. AI use is not split further (no per-employee figure). Read-only. Admin only: a Member is told a workspace admin sees it.
