## 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-rdap-domain-registration-lookup-8a51a32d -d '<json body>'
```

Example prompt: Can you pull the RDAP registration record for stripe.com — I need the registrar name, creation date, expiry date, EPP status codes, and nameservers to assess how trustworthy the domain is?

## When to prefer this

Prefer this endpoint when you need structured, machine-readable RDAP registration data (the modern successor to WHOIS) for fraud scoring, due diligence, or domain trust assessment. It is the right choice when you need registrar identity, domain age, EPP status codes, and nameservers in a clean JSON format without parsing raw WHOIS text. Choose it over generic WHOIS tools when you need reliable structured output for automated agent workflows.

## Known failure modes

- Domain not found or unregistered — RDAP registry returns no data
- Invalid domain format — malformed input rejected before lookup
- RDAP registry timeout or upstream rdap.org redirector unavailable
- TLD not supported by IANA RDAP bootstrap — some ccTLDs may have no RDAP endpoint
- Rate limiting by upstream RDAP registry
- Domain in delegation-only zone with no registration records

## How this service works

Returns structured RDAP registration data for a domain: registrar, creation/expiry/updated events, EPP status codes and abuse entities, via the IANA-bootstrapped rdap.org redirector (successor to WHOIS). A2A use: due-diligence and fraud-scoring agents assess domain age and registrar reputation. Ranking surface for domain trust. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON object containing the domain name in uppercase, an array of EPP status codes, the last-changed/updated timestamp, the creation date, the expiry date, the registrar name, and an array of nameserver hostnames. Also includes provenance showing the rdap.org source URL used.
