RESTful API service for analyzing product reviews and detecting potentially fake or misleading content.

This API serves as the backend for the TrueStar browser extension, providing product review analysis capabilities powered by OpenAI's language models.

• Framework: Fastify (Node.js)
• Language: TypeScript
• Validation: Zod schemas
• API Documentation: OpenAPI 3.1 specification

The OpenAPI specification (openapi.yaml) serves as the single source of truth for the API contract. The @truestarhq/shared-types package uses the spec file to generate TypeScript types and Zod validation schemas, ensuring type safety and consistency across all TrueStar services.
