## 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 datakoot-koot-domain-brief-f48c8737 -d '<json body>'
```

Example prompt: Run a full domain brief on stripe.com — I want to see its registration and DNS info, email security setup (SPF, DKIM, DMARC), what tech stack it uses, and any subdomains showing up in certificate logs.

## When to prefer this

Choose this endpoint when you need a single-call comprehensive domain audit that combines registration, DNS, email security, tech fingerprinting, and subdomain discovery — rather than calling separate specialized APIs for each. Ideal for security due diligence, vendor assessment, phishing investigation, or competitive research where breadth matters more than depth on any single dimension.

## Known failure modes

- Domain does not exist or is unresolvable — returns error with no data
- DKIM lookup may fail if no selector is publicly known
- Certificate transparency logs may show incomplete subdomain coverage for newly registered domains
- Payment not processed if x402 payment fails — no charge and no result
- Rate limiting or timeout if external DNS/WHOIS services are slow

## How this service works

Datakoot Koot: One call checks a domain: registration and DNS, email security (SPF/DKIM/DMARC), tech stack, and subdomains from certificate logs.. $0.01 USDC per brief, charged only on success.

## Output

Returns a structured report including domain registration and WHOIS data, DNS records, email security configuration (SPF, DKIM, DMARC presence and validity), detected web technology stack, and a list of subdomains discovered via certificate transparency logs.
