Domain Expiration Tracker

Checks domain expiration dates via RDAP/WHOIS and optionally sends alerts via Telegram.

Build

go build -o domain-expiration-tracker main.go

Usage

# Single domain
./domain-expiration-tracker -d example.com

# Multiple domains from file
./domain-expiration-tracker -f domains.txt

# Custom threshold (30 days) and delay between checks (120s)
./domain-expiration-tracker -f domains.txt -x 30 -delay 120

Flags

Flag	Default	Description
-d		Domain to check
-f		File with list of domains (one per line, # for comments)
-x	14	Expiration threshold in days
-delay	60	Delay between checks in seconds

Telegram (optional)

Set environment variables to send reports via Telegram. Without these, reports print to console.

export TELEGRAM_TOKEN="your_bot_token"
export TELEGRAM_CHAT_ID="your_chat_id"

How it works

1. Loads RDAP bootstrap from IANA on startup
2. For each domain: tries RDAP first, falls back to WHOIS
3. Reports expired, expiring soon, and available domains
