Frequently Asked Questions

How many domains can I compare at once?

You can compare between 2 and 10 domains in a single request. For larger comparisons, make multiple requests.

What factors determine the recommendation?

Our recommendation algorithm considers availability (highest weight), TLD trust tier, domain valuation, brand score, and popularity rank to generate intelligent suggestions.

What is the difference between best_available and best_overall?

best_available is the highest-ranked domain that is available for registration. best_overall is the highest-ranked domain regardless of availability (useful for acquisition targets).

Does the API check availability in real-time?

Yes! Each comparison checks live availability via RDAP, with intelligent caching for fast responses.
