AI Domain Checker: Fast & Accurate TLD Availability Tool

AI Domain Checker: Fast & Accurate TLD Availability Tool

The AI Domain Checker skill efficiently determines domain availability across any TLD, providing confidence scoring, SSL certificate inspection, and IP resolution information. It operates by leveraging multiple data sources to deliver a binary verdict of "Available" or "Taken," along with detailed insights such as registrar information and SSL certificates when applicable.

What this skill does

• Checks domain availability, confirming whether a domain is Available or Taken.
• Utilizes over five sources in parallel, including RDAP, WHOIS, authoritative DNS lookups, and HTTP reachability.
• Employs DNS A/AAAA and TLS certificate validation to provide comprehensive insights.
• Fetches comprehensive registrar details and SSL certificate information for taken domains.
• Operates in a stateless manner, compatible across Linux, macOS, and Windows.
• Supports both single-domain and bulk asynchronous checks (up to 30 domains in approximately 10 seconds).

Who it is for

• Developers seeking to verify domain availability rapidly and accurately within their projects.
• Tech teams using AI coding agents like Claude Code, Cursor, and Codex who need to integrate domain checks into their workflows.
• IT professionals responsible for managing domain portfolios, ensuring compliance with availability checks.

Use cases

• Determining domain availability before beginning web development projects to avoid conflicts or unnecessary purchases.
• Acquiring comprehensive domain details, such as registrar information and server IPs, for infrastructure planning.
• Verifying SSL certificates and server reachability to enhance security assessments and configurations.

Technical details

• Integrates with RDAP and WHOIS databases, offering TLD-specific patterns and IANA fallback.
• Conducts authoritative DNS server lookups as a GDPR tiebreaker for certain TLDs like .de, .eu, .at, .ch, and .es.
• Includes DNS A/AAAA records and comprehensive SSL certificate examinations.
• Ensures platform-independent functionality across major operating systems without reliance on external libraries.
