❗ Why It Matters

• 🚨 100+ new gTLDs are launched every year — some are risky, some are restricted.
• 📉 Spam and phishing campaigns often use obscure or abused TLDs.
• 🔐 Registrars and platforms need to verify domains before trust is granted.
• 📊 Without structured TLD data, you’re guessing — not filtering.

🔧 Where You Can Use It

Practical ways to use the API to enhance trust, security, and compliance across domain systems.

• Security Tools – Flag suspicious TLDs in threat intel feeds
• SaaS Platforms – Block high-risk signups using shady TLDs
