Example use cases
Pre-outreach email security audit
“Before I start my cold email campaign, check salesforce.com to make sure they have proper DMARC and SPF records set up — I want to know if emails to them are likely to land in the inbox.”
Competitor tech stack research
“What technology stack is shopify.com running? I want to know their CMS, CDN, analytics tools, and any other tech fingerprints you can find.”
Lead enrichment for domain vetting
“I have a lead from the domain acme-widgets.com — can you pull their full domain profile including how old the domain is, what tech they use, and whether their email security looks legit?”

Endpoint
GEThttps://domaindna-api.cybermax-tools.workers.dev/x402/api/registration?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive single-call lookup combining tech stack fingerprinting, email security posture, and domain age for any website or domain. It is ideal over separate DNS, WHOIS, and tech-detection tools because it bundles all three into one call with evidence, reducing latency and cost. Best for lead enrichment, security audits, pre-outreach vetting, and competitive research.
Side effects
- Domain not found or unresolvable returns empty or error response
- Rate limiting if more than 10 domains submitted per call
- Invalid domain format returns validation error
- Private or newly registered domains may have incomplete RDAP data
- Some tech stack fingerprints may be absent if the site blocks crawlers
