Frequently Asked Questions

What is a TLD trust score?

Trust scores (0-100) reflect how trustworthy and established a TLD is. Premium TLDs like .com and .io have high scores, while newer or less-known TLDs have lower scores.

How accurate is the pricing information?

Pricing is based on market averages and may vary by registrar. Use it as a guideline - always check with your preferred registrar for exact pricing.

Can I filter TLDs by use case?

Yes! Use the use_case parameter (e.g., ?use_case=startup) to get TLDs recommended for specific purposes.

What is the difference between gTLD and ccTLD?

gTLDs (generic TLDs) like .com and .org are not tied to any country. ccTLDs (country code TLDs) like .uk and .de are assigned to specific countries but many allow global registration.
