Direct credit consumption
  • Added: an endpoint to consume credits directly from a customer’s pool, without reporting usage against a metered feature or requiring an active subscription. Complements the existing grant-credits endpoint so credit balances, grants, and consumption can be managed fully decoupled from Stigg subscription management. See direct credit consumption.
  • The check-entitlement endpoint continues to return a valid credit balance for customers with no active subscription.
​

Credit wallet soft limit
  • Added: has_soft_limit field on check-entitlement responses. When a credit entitlement is configured as a soft limit in the plan or add-on, the check-entitlement endpoint returns has_access: True and has_soft_limit: True even after the credit balance reaches zero. Hard limit (the default) continues to return has_access: False when the balance is exhausted. Credit-backed features inherit the wallet’s soft-limit so dependent feature reads stay consistent.
