Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent402-tools-domain-intel-e819ba44 -d '<json body>'
```

Example prompt: Run a full domain intel sweep on stripe.com — I want WHOIS, DNS records, TLS cert details, HTTP security headers, tech stack, robots policy, and certificate transparency all at once.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-faceted domain investigation in a single call rather than calling individual WHOIS, DNS, or TLS APIs separately. It is ideal for security audits, due diligence on an unknown domain, competitive SEO research, or threat intelligence workflows where breadth of signal matters and minimizing round-trips is important. Prefer it over individual lookup tools when you need 6+ data dimensions simultaneously.

## Known failure modes

- Domain does not exist or is unresolvable — partial or empty results for DNS/TLS sections
- WHOIS rate-limiting or privacy-protected registrant — redacted WHOIS fields
- TLS handshake failure for domains without HTTPS — missing cert data
- Payment failure via x402 — 402 response before any data is returned
- Timeout on one or more underlying tools — partial result set returned

## How this service works

Bundled execution of the Domain intel workflow - Full domain security and SEO intelligence in one call: WHOIS, DNS, TLS cert, HTTP headers, tech stack, robots policy, and certificate transparency. One x402 payment runs 6 underlying tools (whois, dns-lookup, tls-cert, http-headers, tech-stack, robots-check); partial-success per step.

## Output

A bundled report containing: WHOIS registration data (registrar, dates, registrant), DNS records (A, MX, NS, etc.), TLS/SSL certificate details (issuer, expiry, SANs), HTTP response headers (security headers like HSTS, CSP), detected technology stack, robots.txt directives, and certificate transparency log entries — all from a single API call.
