Frequently Asked Questions about fastapi-backend

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a production-grade FastAPI backend with JWT authentication?

Use FastAPI with SQLModel schemas, Pydantic v2 validation, and JWT/JWKS verification to create secure REST APIs. This Skill automates backend scaffolding with authentication patterns, Neon PostgreSQL integration, and OpenAPI documentation.

Can I use FastAPI with SQLModel for database-backed APIs?

Yes. SQLModel combines SQLAlchemy and Pydantic to define database schemas and API models in one. This Skill provides SQLModel integration with Neon PostgreSQL, CRUD endpoints, and audit logging for production APIs.

How do I implement JWT and JWKS verification in FastAPI?

JWT/JWKS verification validates signed tokens from identity providers like Better Auth. This Skill automates token validation setup, role-based access control, and secure endpoint protection in FastAPI applications.

What's the best way to structure FastAPI REST endpoints with OpenAPI contracts?

Define Pydantic models for request/response schemas and use FastAPI's automatic OpenAPI generation. This Skill provides endpoint patterns, audit logging, and documentation standards for production REST APIs.

Does FastAPI work with Neon PostgreSQL for scalable backends?

Yes. FastAPI pairs with Neon's serverless PostgreSQL via SQLModel and connection pooling. This Skill handles Neon integration, schema setup, and CRUD operations for production backends.

How do I ensure API parity between human and agent use in FastAPI?

Design consistent request/response contracts and validation rules accessible to both. This Skill provides OpenAPI documentation, RBAC patterns, and audit logging to maintain human-agent parity in production.
