## 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 domain-intelligence-lookup-whois-dns-ssl-16fcf181
```

Example prompt: Can you do a full domain intelligence lookup on openai.com — I want to see the WHOIS registration info, DNS records, and SSL certificate details all in one go?

## When to prefer this

Use this endpoint when you need a single-call aggregation of WHOIS, DNS, and SSL data for a domain, rather than querying three separate services. Ideal for domain research, security investigations, due diligence on unfamiliar domains, or verifying domain ownership and certificate validity in one step.

## Known failure modes

- Domain not found or unregistered — empty or error response
- Invalid domain format — malformed input rejected
- WHOIS data unavailable for privacy-protected or redacted domains
- DNS lookup timeout for unreachable or nonexistent domains
- SSL certificate absent for non-HTTPS domains

## How this service works

Get comprehensive domain intelligence (WHOIS + DNS + SSL) (POST variant)

## Output

A comprehensive domain intelligence report combining WHOIS registration data (registrar, registrant, creation/expiry dates), DNS records (A, MX, NS, TXT, etc.), and SSL certificate information (issuer, validity, SANs) for the queried domain
