SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

The skill automates domain availability checks and registration lookups so users can quickly find, verify, and research domain names without manual WHOIS parsing or external API keys.

Core Features & Use Cases

  • RDAP-first availability checks across 1195+ gTLDs with structured JSON results and authoritative 404 handling.
  • whois CLI fallback for TLDs without RDAP support (e.g., .io, .co, .me) with pattern matching to detect availability, registrar, dates, and nameservers.
  • Bulk and parallel processing with thread pooling, bootstrap caching, rate-aware batching, expiry and nameserver extraction for branding, domain purchasing decisions, or asset audits.
  • Use Case: Search a keyword across common TLDs to surface available brand names and retrieve registrar/expiry data for selected domains.

Quick Start

Check if mybrand.com,mybrand.io and mybrand.ai are available and return registrar, expiration date, and nameservers.

Frequently Asked Questions about domain-research

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

FAQPage Schema
How do I check domain availability across multiple TLDs without an API key?▼

You can check domain availability without an API key by using the IANA RDAP bootstrap and registry RDAP servers. This approach queries 1195+ gTLDs and common ccTLDs, returning structured JSON results with authoritative 404 handling for available domains.

Can I perform a bulk WHOIS lookup and extract registrar and expiry dates for many domains at once?▼

Yes, bulk WHOIS lookup is supported through thread pooling and parallel queries with rate-aware batching. This allows you to extract registrar information, expiration dates, and nameservers efficiently for domain asset audits or purchasing decisions.

How does RDAP domain lookup work when a TLD lacks RDAP support?▼

When a TLD lacks RDAP support, the domain lookup falls back to a whois CLI tool. This fallback uses pattern matching to detect domain availability, registrar details, registration dates, and nameservers for TLDs like .io, .co, or .me.

What is the best way to find available brand names using keyword-based TLD searches?▼

The best way to find available brand names is to search a keyword across common TLDs to surface available domains. This process retrieves registrar and expiry data for selected domains, helping you verify and research domain names quickly.

Are there limitations when checking domain registration details for ccTLDs?▼

Limitations exist when checking domain registration details for ccTLDs without RDAP support, requiring a whois CLI fallback. While pattern matching extracts registrar and nameserver data, the structured JSON output and authoritative 404 handling are limited to RDAP-supported TLDs.
