How this service works
Any website's tech stack and email security, one call. Tech stack, email security and domain age API + MCP: one call per domain, evidence included Try it free in one click, no sign-up.
Output
A JSON object containing the detected technology stack (CMS, CDN, frameworks, analytics, hosting, etc.) with evidence, email security DNS records (DMARC, SPF, DKIM), domain registration age via RDAP, and other DNS signals — all from a single call per domain or up to three comma-separated domains.
Example use cases
Competitor tech stack reconnaissance
“I'm evaluating our competitors — can you pull the full tech stack for shopify.com and tell me what frontend frameworks, CDN, analytics tools, and ecommerce platforms they're running?”
Email security audit before cold outreach
“Before we start our email campaign targeting leads at acme.com, can you check whether that domain has proper DMARC, SPF, and DKIM records set up so we know if our emails are likely to land in their inbox?”
Domain trustworthiness check for vendor vetting
“We're considering onboarding a new vendor at quickinvoice.io — can you check how old that domain is and what technology stack it runs so I can assess whether it looks like a legitimate, established business?”
Technical details
Endpoint
GEThttps://domaindna-api.cybermax-tools.workers.dev/x402/api/tech?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, single-call snapshot of a domain's technology fingerprint and email security posture together. It is ideal for OSINT, vendor vetting, competitive intelligence, or pre-outreach domain checks where you want both tech stack and email authentication data without separate lookups. Prefer this over generic WHOIS or tech-detection tools when you need evidence-backed results and email security (DMARC/SPF/DKIM) combined with domain age in one response.
Side effects
- Domain not found or unreachable — DNS lookup fails with no data returned
- Invalid domain/URL/email input format — returns validation error
- Private RDAP records — domain age may be unavailable for some TLDs
- Partial results — some tech stack components may not be detected if the site blocks scanners
- Rate limit or payment failure via x402 — call rejected before execution
