## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability domaindna-domain-tech-stack-email-security-report-be2b0edf
```

Example prompt: Can you pull up the full DomainDNA report for stripe.com — I want to see their tech stack, email security records like SPF and DMARC, and how old the domain is?

## When to prefer this

Choose this endpoint when you need a single-call, all-in-one domain intelligence report combining tech stack fingerprinting, email security validation, and domain age — especially useful for security assessments, vendor due diligence, competitive research, or phishing investigation. Prefer over separate DNS lookup, WHOIS, or technology detection tools when breadth and convenience matter more than deep specialization in any single dimension.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Invalid input (malformed domain/URL/email) — validation error
- Domain exists but has no detectable tech stack — returns empty tech array
- DMARC/SPF records absent — fields returned as null or missing
- Payment not processed (x402 protocol failure) — request blocked
- Rate limiting or worker timeout for slow-responding domains

## 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 structured JSON report containing: detected technologies used by the website (CMS, frameworks, CDN, analytics, etc.), email security records (SPF, DKIM, DMARC policies with evidence), domain registration age via RDAP, and supporting DNS evidence for all findings.
