# pounce — Domain Availability Monitoring

A professional full-stack application for monitoring domain name availability with TLD price tracking and intelligence.

---

## ⚠️ Important: After Fresh Clone / Database Reset

If you just cloned the repo or reset the database, run these commands to populate data:

```bash
cd backend
source venv/bin/activate

# 1. Initialize database (creates tables)
python scripts/init_db.py

# 2. Scrape TLD prices (886+ TLDs from Porkbun)
python scripts/seed_tld_prices.py

# 3. (Optional) Scrape auctions immediately
python3 -c "
import asyncio
from app.services.auction_scraper import AuctionScraperService
from app.database import AsyncSessionLocal

async def scrape():
    scraper = AuctionScraperService()
    async with AsyncSessionLocal() as db:
        await scraper.scrape_all_platforms(db)
    await scraper.close()

asyncio.run(scrape())
"
```

Without these steps:
- TLD Pricing page shows only 18 TLDs (instead of 886+)
- Auctions page shows 0 auctions
- The scheduler will auto-scrape TLDs daily at 03:00 UTC and auctions hourly

| Method | Endpoint | Description |
|--------|----------|-------------|
| GET | `/api/v1/domains` | List watched domains |
| POST | `/api/v1/domains` | Add domain to watchlist |
| DELETE | `/api/v1/domains/{id}` | Remove domain |
| POST | `/api/v1/domains/{id}/refresh` | Refresh domain status |
| GET | `/api/v1/domains/{id}/history` | Get check history |

### TLD Prices
| Method | Endpoint | Description |
|--------|----------|-------------|

| GET | `/api/v1/tld-prices/{tld}/history` | Get price history |
| GET | `/api/v1/tld-prices/{tld}/compare` | Compare registrar prices |

#### Price Data Consistency

All TLD price endpoints use a unified pricing strategy:

1. **Static TLDs (18 popular)**: Rich multi-registrar data (5+ registrars per TLD)
   - .com, .net, .org, .io, .ai, .dev, .app, .xyz, .tech, .online, .store, .me, .info, .biz, .ch, .de, .uk, .co
   
2. **Database TLDs (869+)**: Scraped from Porkbun API (single registrar)

**Price Calculation** (consistent across all endpoints):
```
avg_price = sum(registrar_prices) / count(registrars)
min_price = min(registrar_prices)
max_price = max(registrar_prices)
```

This ensures identical prices on:
- Overview table (`/overview`)
- Detail page (`/{tld}`)

## Production Deployment

### Docker (Recommended)

```bash
# Clone repository
git clone https://git.6bit.ch/yvg/pounce.git
cd pounce

# Set environment variables
export SECRET_KEY=$(python3 -c "import secrets; print(secrets.token_hex(32))")

# Build and start
docker-compose up -d --build
```

### Manual Deployment

See [DEPLOYMENT.md](./DEPLOYMENT.md) for detailed instructions including:
- Systemd service setup
- PM2 for Node.js
- Nginx reverse proxy configuration
- SSL/HTTPS with Let's Encrypt
- PostgreSQL database setup

---

## Domain Checking Methods

pounce uses multiple methods to verify domain availability:

1. **Custom RDAP** — For TLDs with own RDAP servers (e.g., `.ch`, `.li` via `rdap.nic.ch`)
2. **RDAP via whodap** — Modern protocol with detailed data, supported by major registries
3. **WHOIS (Fallback)** — Traditional protocol for domains without RDAP support
4. **DNS (Quick check)** — Fast initial availability check via DNS queries

The system automatically falls back to the next method if one fails.

### Supported TLDs with Custom RDAP

| TLD | RDAP Server | Notes |
|-----|-------------|-------|
| `.ch` | `rdap.nic.ch` | Swiss domains - WHOIS blocked |
| `.li` | `rdap.nic.ch` | Liechtenstein - same registry |

### Standard RDAP TLDs

`.com`, `.net`, `.org`, `.info`, `.biz`, `.io`, `.co`, `.ai`, `.app`, `.dev`, `.xyz`, `.me`, and many more.

---

## TLD Price Scraping

pounce automatically scrapes TLD prices from public sources for price intelligence and trend tracking.

### Data Source

**Primary:** Porkbun Public API (no API key required!)

```
POST https://api.porkbun.com/api/json/v3/pricing/get
```

- ✅ **886+ TLDs** with pricing
- ✅ Registration, Renewal, Transfer prices
- ✅ No authentication needed
- ✅ Updated daily via scheduler

### Scheduler Jobs

| Job | Schedule | Description |
|-----|----------|-------------|
| **Domain Check** | Configurable (default: daily) | Checks all watched domains |
| **TLD Price Scrape** | Daily at 03:00 UTC | Scrapes current TLD prices |
| **Price Change Alerts** | Daily at 04:00 UTC | Sends email for price changes >5% |

### Manual Scrape

Trigger a manual TLD price scrape:

```bash
curl -X POST http://localhost:8000/api/v1/admin/scrape-tld-prices
```

Response:
```json
{
  "message": "TLD price scrape completed",
  "status": "success",
  "tlds_scraped": 886,
  "prices_saved": 886,
  "sources_succeeded": 1
}
```

### Database Stats

Get current TLD price data statistics:

```bash
curl http://localhost:8000/api/v1/admin/tld-prices/stats
```

Response:
```json
{
  "total_records": 886,
  "unique_tlds": 886,
  "unique_registrars": 1,
  "latest_record": "2025-12-08T08:04:54",
  "data_range_days": 0
}
```

### Price Data Model

```python
TLDPrice:
  - tld: str              # e.g., "com", "io", "ai"
  - registrar: str        # e.g., "porkbun"
  - registration_price: float
  - renewal_price: float
  - transfer_price: float
  - currency: str         # "USD"
  - recorded_at: datetime # For historical tracking
```

### Future Data Sources

The scraper architecture supports multiple sources:

1. **Porkbun API** ✅ (active)
2. **TLD-List.com** (blocked - placeholder)
3. **Namecheap Affiliate** (requires signup)
4. **Cloudflare** (requires account)

SMTP_FROM_EMAIL=hello@pounce.ch
SMTP_FROM_NAME=pounce
SMTP_USE_TLS=false
SMTP_USE_SSL=true
CONTACT_EMAIL=hello@pounce.ch
```

Alternative providers:
```env
# Gmail (port 587, STARTTLS)
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_USE_SSL=false
SMTP_USE_TLS=true
```

## Development

### Backend

```bash
cd backend
source venv/bin/activate

# Run with auto-reload
uvicorn app.main:app --reload

# API docs available at:
# http://localhost:8000/docs (Swagger)
# http://localhost:8000/redoc (ReDoc)
```

### Frontend

```bash
cd frontend

# Development server
npm run dev

# Lint
npm run lint

# Build for production
npm run build

# Start production server
npm start
```

---

## Troubleshooting

### Backend won't start

1. Check Python version: `python3 --version` (needs 3.12+)
2. Ensure virtual environment is activated
3. Check `.env` file exists and has valid `SECRET_KEY`
4. Check for syntax errors in config files

### Frontend can't connect to backend

1. Ensure backend is running on port 8000
2. Check `NEXT_PUBLIC_API_URL` in `.env.local`
3. Verify CORS origins in backend `.env`
4. Check browser console for CORS errors

### Domain checks failing

1. Some TLDs may have rate limits
2. Certain ccTLDs require special handling (see below)
3. Check backend logs for specific errors

**Swiss/Liechtenstein domains (.ch, .li):**
- WHOIS is blocked for automated requests
- pounce uses the official `rdap.nic.ch` API instead
- This is automatic - no configuration needed

**Other ccTLDs:**
- Some country code TLDs don't support RDAP
- pounce falls back to DNS checking
- Results may be less detailed (no registrar info)

### Database errors

1. Delete `domainwatch.db` to reset (dev only)
2. Check database URL format in `.env`
3. Ensure write permissions on database directory
