A dependable AI SaaS product needs more than a model endpoint. The first unit establishes a FastAPI backend with configuration, database models, users, API keys, credits, JWT access tokens, authentication middleware, and protected routes. Readers see how account data, credential checks, authorization failures, and service logic fit together as a coherent application foundation.
The next stage extends those services into frontend experiences for registration, login, account management, API keys, and credit balances. Testing connects the client and server before billing work begins. Stripe integration then introduces products, prices, checkout, payment records, event verification, webhooks, and billing pages, with attention to how data moves through the complete user flow.
By the end of this guide, readers can assemble and test the core systems behind an AI SaaS application. They will understand how authentication, usage credits, protected APIs, payments, database checks, and frontend interactions work together to support a more deployable product.
