Domain Search API Suites, One Key
Every suite shares one API key, one JSON style and one credit balance. Use them over REST or through the MCP server.
Web Data
Pull titles, meta tags, tech stack hints and page status for any URL.
Domain Intelligence
WHOIS and RDAP records, availability, registrar and domain age.
DNS & Infrastructure
A, AAAA, MX, NS, TXT and CNAME records, plus IP and hosting details.
Security & Trust
SSL certificate details, expiry, blocklist status and lookalike domain checks.
Identity & Verification
Email syntax, MX and deliverability signals, plus domain ownership hints.
Monitoring & Automation
Watch domains for DNS, WHOIS or certificate changes and get notified.
One consistent response format
Every suite returns clean JSON with predictable field names, so you can switch from a WHOIS lookup to a DNS check without a new parser.
