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)

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

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

Manual Deployment

See 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:

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

Response:

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

Database Stats

Get current TLD price data statistics:

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

Response:

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

Price Data Model

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)

---

Email Notifications

pounce supports automated email notifications for domain availability and price changes.

Setup

Configure SMTP settings in your .env:

SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_USER=your-email@gmail.com
SMTP_PASSWORD=your-app-password

Notification Types

Type	Trigger	Description

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

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
