# Quoter 🚀

> Simple file upload proxy with quotas. Upload to S3, thumbnails via Vercel.

**Focus**: Upload + Storage. Thumbnails managed by Vercel Edge API for better performance.

## What it does

- 📤 **Upload files** to S3/Storj with user quotas
- 🔐 **JWT authentication** with session management  
- 📦 **File serving** with caching and optimization
- 🌐 **CORS support** for web apps 

## 🚀 Quick Start

```bash
# Setup
cargo build
cp .env.example .env  # Configure environment
cargo run

# Test
curl http://localhost:8080/  # Health check
```

## 🔧 API

| Method | Endpoint | Description |
|--------|----------|-------------|
| `GET` | `/` | Health check or user info (need auth token) |
| `POST` | `/` | Upload file (need auth token) |
| `GET` | `/{filename}` | Get file or thumbnail |

### Upload file
```bash
curl -X POST http://localhost:8080/ \
  -H "Authorization: Bearer your-token" \
  -F "file=@image.jpg"
```

### Get thumbnail
```bash
# Legacy thumbnails (fallback only)
curl http://localhost:8080/image_300.jpg

# 💡 Recommended: Use Vercel Image API

```

## 🏗️ Architecture & Setup

**Simple 3-tier architecture:**
- **Upload**: Quoter (auth + quotas + S3 storage)
- **Download**: Vercel Edge API (thumbnails + optimization)  
- **Storage**: S3/Storj (files) + Redis (quotas/cache)

```
Upload: Client → Quoter → S3/Storj
Download: Client → Vercel → Quoter (fallback)
```

💋 **Simplified approach**: Quoter handles uploads, Vercel handles thumbnails.
