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, analytics, frameworks, etc.) with supporting evidence, email security DNS records (SPF, DKIM, DMARC) and their validity, domain registration age, and RDAP/WHOIS-derived metadata — all from a single request per domain.
Example use cases
Vendor security due diligence
“Before we onboard this new supplier, can you check vendoracme.com's email security — specifically whether they have SPF and DMARC set up — and tell me how old the domain is so I can flag any red flags?”
Competitor technology research
“I'm doing competitive research — can you find out what tech stack, frameworks, and infrastructure shopify.com is using?”
Phishing domain vetting
“I just received an email from someone at payments-secure-invoices.com — can you check that domain's age, tech stack, and whether it has any real email security records like DMARC and SPF to help me decide if it's legit?”
Technical details
Endpoint
GEThttps://domaindna-api.cybermaxtools.com/x402/api/tech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined one-call lookup of technology stack, email security posture, and domain age for any domain — it saves multiple separate DNS, WHOIS, and crawl calls. Prefer it over individual DNS lookup tools, BuiltWith-style tech detectors, or WHOIS lookups when you want consolidated evidence-backed results in a single request for up to 3 domains at once.
Side effects
- Domain not found or unresolvable — returns error or empty tech stack
- Private/redacted WHOIS may result in missing domain age
- Domains behind strict WAFs may return incomplete tech fingerprints
- Invalid input format (non-domain string) may return a validation error
- Rate limiting if querying more than 3 domains per call or in rapid succession
