Credits and Subscriptions

Image generation cost varies by model, retry count, storage, and output size. Credits make usage predictable while subscriptions support repeat customers.

Credit Consumption

Each generation task can consume a configured number of credits. The API should check available balance before accepting the job.

Recurring Plans

Subscriptions can grant credits at the start of each billing period. Renewal webhooks create the next cycle payment record and issue credits after the provider event is verified.

Access State

Cancelations, failed renewals, and refunds should update entitlements so the generator reflects the user’s current billing state.
