SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill eliminates the need for paid domain research tools or API credentials to check domain availability, ownership, and registration details, saving you time and money on domain-related research for personal or business projects.

Core Features & Use Cases

  • Free, no-credential checks: Queries 1195+ TLDs via RDAP with a whois CLI fallback for unsupported TLDs, no API keys or setup required.
  • Comprehensive lookup support: Check single or bulk domain availability, search for domains matching a keyword across TLDs, retrieve full WHOIS/RDAP registration details, check expiration dates, and get nameserver information.
  • Use Case: If you are launching a new startup and need to find an available brand domain, use this Skill to quickly check availability across .com, .io, .ai and other popular TLDs, or look up expiration dates of competitor domains to identify potential acquisition opportunities.

Quick Start

Use the domain-research skill to check if the domain 'mynewstartup.com' is available and find 5 alternative available domains with the .ai or .dev TLD.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check domain availability without paid API keys?▼

You can check domain availability without paid API keys by using the RDAP protocol across 1195+ TLDs, with a whois CLI fallback for unsupported TLDs. This approach queries registration servers directly, requiring zero credentials or setup.

Can I perform bulk domain checks for multiple TLDs?▼

Yes, you can perform bulk domain checks across multiple TLDs using parallel lookups for speed. The tool searches available domains matching a keyword across 1195+ TLDs and returns structured availability results without requiring user credentials.

What is the difference between RDAP and WHOIS lookups for domain research?▼

RDAP is the modern protocol used for querying domain registration data across 1195+ TLDs, while WHOIS CLI acts as a fallback for unsupported TLDs. Using RDAP first ensures broad coverage and structured output, with whois filling the gaps.

How do I find available domains matching a keyword across different extensions?▼

To find available domains matching a keyword, you can search across 1195+ TLDs using the keyword-based domain search feature. This checks availability across extensions like .com, .io, and .ai, returning structured results for available matches.

Does this domain research tool retrieve nameservers and expiration dates?▼

Yes, the domain research tool retrieves nameservers and expiration dates as part of the full WHOIS/RDAP registration details. It queries the RDAP protocol directly to fetch and return structured registration data for registered domains.

What are the limitations of using RDAP for domain lookups?▼

A limitation of using RDAP is that not all TLDs support the protocol, requiring a whois CLI fallback for unsupported extensions. Additionally, RDAP queries depend on direct server availability and may face rate limits or lack data for certain ccTLDs.
