# Cancel Preview

`GET /api/billing/cancel/preview`

Show the user what their final invoice will be if they cancel now.

C-2 (BILLING_RULES.md Sections 1 + 7): the final invoice is the sum of
PrimeTime's half of cumulative lift across all unbilled attributions, not
RPM × incremental_views. Pulled directly from optimization_attribution
rows that AttributionEngine already wrote.

Read-only. Does not change any state.
