Enable or disable usage-based billing for your account. When disabled, the Revenium app hides your account's billing screens (invoices, payment methods, plan and subscription screens) and your account's usage stops being rated: AI product usage, its platform usage and /v2/events produce no usage line items. Usage that arrives while it is disabled is never rated, including after it is enabled again. AI metrics are still recorded, and subscription charges are unaffected. Defaults to disabled.

The same value is exposed on the account summary returned by GET /v2/api/users/me, which is where the Revenium app reads it before first paint.
