Find Available Domain Names
Search for available domain names that match your brand, project, or business idea.
Quick answer: Use the Domain Search tool through ToolRouter to find available domain names directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolChoosing the right domain name is one of the first decisions in any online project. A good domain is memorable, relevant, and actually available. Manually checking domains one by one across registrars is tedious, and the best names go fast. You need a way to search broadly and quickly identify what is still open.
The search_domains skill lets you query for domain availability across multiple TLDs in one call. Provide a keyword or brand name and get back a list of available options -- .com, .io, .dev, .co, and more. The results show availability status and pricing so you can make a decision without visiting five different registrar websites.
This is essential for startup founders picking a company name, developers launching side projects, marketers setting up campaign microsites, and agencies securing domains for clients. Search once, see everything available, and move fast before someone else registers the name you want.
