canyougrab.it is a REST API for checking domain name availability in bulk. Send up to 100 domains in a single API call and get structured JSON results with availability status, confidence scores, and registration details.
Unlike traditional WHOIS lookups (limited to one domain at a time and heavily rate-limited), canyougrab.it queries DNS servers directly with WHOIS as a fallback โ the same sources registrars use โ giving you real-time, reliable results at scale.
Key features: - Bulk checking: up to 100 domains per request - Live DNS + WHOIS lookups (not stale zone files) - Clean JSON responses with availability, confidence, TLD, and data source - Generous rate limits (up to 3,000 req/min on Business plan) - Free tier to get started (500 lookups/month) - RESTful API with Bearer token auth
Built for domain hunters, SaaS builders, registrar integrations, and anyone who needs to validate domains at scale.
