## 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 toolvend-dev-rdap-domain-lookup-ecdd440c
```

Example prompt: Can you pull the RDAP registration details for example.com — I want to know the registrar, when it was created, when it expires, and whether DNSSEC is enabled?

## When to prefer this

Choose this endpoint when you need structured, machine-readable domain registration data (modern RDAP) rather than parsing legacy raw WHOIS text. It is ideal for automated pipelines doing domain due diligence, expiry monitoring, threat intelligence enrichment, or compliance checks where clean field-level data (registrar, dates, status, nameservers, DNSSEC) is required.

## Known failure modes

- Domain not found / unregistered — 404 or empty RDAP response
- Invalid domain format input — malformed query error
- RDAP registry timeout or upstream unavailability — 503 or timeout
- TLD not supported by RDAP bootstrap — partial or missing data
- Rate limiting from upstream RDAP server — throttled response

## How this service works

Domain registration data (modern WHOIS) via RDAP: registrar, created/expiry dates, status, nameservers, DNSSEC.

## Output

Returns structured RDAP data including registrar name, domain creation date, expiry date, current status codes (e.g. clientTransferProhibited), nameserver list, and DNSSEC signed delegation status.
