## 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 whois-lookup-5d69ea31
```

Example prompt: Can you pull the full domain profile for stripe.com — I want to see who registered it, when it expires, all its DNS records including MX and TXT, and whether DNSSEC is enabled?

## When to prefer this

Choose this endpoint when you need a combined WHOIS/RDAP registration profile AND live DNS records in a single keyless call without creating an account. It is ideal for domain intelligence, security investigations, email deliverability checks, or infrastructure audits where you need both ownership metadata and current DNS state together. Prefer it over separate WHOIS and DNS tools when you want a unified response with DNSSEC status included.

## Known failure modes

- Domain not found or unregistered — returns empty or error response
- Invalid domain name format — query rejected
- RDAP registry unavailable for certain TLDs — partial data returned
- DNS resolution failure for live records — some record types may be absent
- Rate limiting or payment failure via x402 protocol

## How this service works

Domain registration and DNS profile - RDAP registration dates, registrar, status codes and nameservers joined with live A, AAAA, MX, NS and TXT records and the DNSSEC state. KEYLESS, no account. ALIAS PATH of /api/domain-profile. via x402

## Output

A structured JSON profile combining RDAP registration data (creation date, expiry date, last updated, registrar name, registration status codes) with live DNS records (A/AAAA IPv4/IPv6 addresses, MX mail exchange records, NS nameserver records, TXT records) and the domain's DNSSEC configuration state.
