## 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 synthora-dns-whois-domain-report-cee51523 -d '<json body>'
```

Example prompt: Can you run a full DNS and WHOIS report on example.com — I want to see all the DNS records, registrar info, expiration date, and a hygiene score so I know if the domain is properly configured?

## When to prefer this

Use this endpoint when you need a single, comprehensive domain report combining DNS records, WHOIS/RDAP registration data, and a computed hygiene score in one call. Prefer it over separate DNS or WHOIS tools when you want a holistic view of domain health, including security posture (DNSSEC, SPF, DMARC, registrar lock). The Ed25519 signature makes it suitable for audit or compliance contexts requiring verifiable results.

## Known failure modes

- Domain not found or does not exist — empty or error response for unregistered domains
- Invalid input format — malformed domain, URL, or email address rejected
- DNS resolution failure — upstream DNS-over-HTTPS provider unavailable
- RDAP/WHOIS data unavailable — some TLDs or registrars may not support RDAP
- Payment failure — x402 USDC payment not processed or insufficient balance

## How this service works

Full DNS + WHOIS/RDAP domain report in one call. Resolves A, AAAA, MX, TXT, NS, CNAME, SOA and DNSSEC over DNS-over-HTTPS, plus structured WHOIS via RDAP (registrar, registration/expiration/updated dates, EPP status, nameservers), and returns a 0-100 domain-hygiene score with letter grade (age, days-to-expiry, nameserver redundancy, MX presence, DNSSEC, SPF/DMARC, registrar lock). Deterministic, Ed25519-signed. $0.001 USDC via x402 on Base. SYNTHORA.

## Output

A signed JSON report containing resolved DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA, DNSSEC), structured WHOIS/RDAP data (registrar, registration/expiration/updated dates, EPP status, nameservers), and a 0-100 domain hygiene score with a letter grade reflecting age, days-to-expiry, nameserver redundancy, MX presence, DNSSEC, SPF/DMARC, and registrar lock status. The response is deterministic and Ed25519-signed.
