# API Overview

> The Builder Box uses tRPC and Hono for type-safe API communication between the client and server. This documentation will guide you through setting up, using, and extending the API.

## API Types

Our API is organized into three main types of routes:

<CardGroup cols={3}>
  <Card title="Public Routes" icon="globe" href="/api-setup/public">
    Routes accessible without authentication for public data access, health checks, and authentication endpoints.
  </Card>

  <Card title="Protected Routes" icon="lock" href="/api-setup/protected">
    Routes requiring user authentication for user-specific data, profile management, and personal settings.
  </Card>

  <Card title="Subscribed Routes" icon="star" href="/api-setup/subscribed">
    Routes requiring an active subscription for premium features and subscription-gated content.
  </Card>
</CardGroup>

## Key Features

* Full type safety between client and server
* Built-in request validation
* Easy error handling
