1. Buy only the credit you choose
The billing page starts a Stripe-hosted prepaid checkout. Settled purchased credit becomes eligible for managed inference; the gateway does not expose Stripe credentials or card details.
2. Activate the approved managed provider
Onboarding or Providers can activate the current managed Bedrock catalog without a provider key. The release pipeline validates the exact model, region, catalog price, IAM scope, guardrail path, and a bounded paid canary before publication.
3. Apply a workload limit
Create the route, policy, budget, and one-time workload key. Managed requests reserve both the general wallet and the purchased-cash eligibility balance before AWS invocation. At zero eligible balance, the request stops before provider spend unless the owner has separately enabled capped automatic reload.
