## 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-intel-rdap-dns-a2994db7
```

Example prompt: Can you pull up the full registration details for suspicious-phishing-site.com — I want to know who registered it, when it was created and expires, what nameservers it uses, whether DNSSEC is enabled, and any red-flag status indicators?

## When to prefer this

Choose this endpoint when you need comprehensive domain registration intelligence in a single call — combining RDAP (registrar, dates, statuses, DNSSEC) with a live DNS summary and derived anomaly flags. Prefer it over raw WHOIS tools when you want structured, machine-readable output with derived signals, or when investigating suspicious domains for threat intelligence, fraud, or due diligence workflows.

## Known failure modes

- Domain not found in RDAP — returns 404 or empty result for unregistered or unsupported TLDs
- RDAP registry unavailable — upstream timeout or 5xx propagated
- Invalid domain format — malformed input rejected
- DNS resolution failure — DNS summary portion may be incomplete if resolvers time out
- Stale cache — data up to 24h old may not reflect very recent registration changes

## How this service works

RDAP registration card (dates, registrar, statuses, nameservers, DNSSEC) + derived flags + inline DNS summary — cached ≤24h

## Output

Returns an RDAP registration card including creation/expiry/updated dates, registrar name, domain lifecycle statuses, nameservers, DNSSEC configuration, plus derived risk/anomaly flags and an inline DNS record summary. Data is cached for up to 24 hours.
