In the second part of a series on AI API monetization, the focus is on configuring Moesif for pricing, metering, access control, and governance. After setting up the AI API with AWS Lambda, Gateway, and Stripe integration in the previous article, this installment guides users through creating pricing plans and billing meters for input and output tokens within Moesif's Product Catalog, which automatically syncs with Stripe. The process includes setting up pricing models, metering API usage, and enforcing access rules using Moesif Governance Rules to block API access for users with zero prepaid balance or overdue invoices. These steps ensure that API providers can accurately bill users for their usage and implement restrictions as needed. The article concludes by outlining how the established infrastructure allows for confident billing and control over API access, setting the stage for the next tutorial, which will cover adding credits to user accounts.
