Overview
DomainsDB.info provides a searchable database of registered domain names, allowing you to find all domains containing specific keywords, phrases, or patterns across various TLDs. It is useful for brand monitoring, competitive research, and discovering domain availability trends. No authentication is required for basic searches.
Beginner Tip
This is a simple GET-based API — just pass a search term as a query parameter and receive a list of matching registered domains. It covers hundreds of TLDs and is updated regularly. Use the domain parameter to filter by keyword and zone to narrow by TLD (e.g., com).
Available Data

const data = await response.json();
console.log(data); What Can You Build?
