## 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 aurenic-whois-rdap-lookup-cc139b2a
```

Example prompt: Can you do a WHOIS lookup on openai.com and tell me who the registrar is, when it was registered, and when it expires?

## When to prefer this

Choose this endpoint when you need structured WHOIS/RDAP data for a specific domain at low cost ($0.001/call) without setting up your own WHOIS infrastructure. Ideal for agents doing domain research, brand monitoring, fraud detection, or pre-acquisition due diligence. Prefer over manual WHOIS tools when automation and programmatic access are required.

## Known failure modes

- Domain not found or unregistered — may return empty or error response
- Invalid domain format — malformed input may cause a 4xx error
- TLD not supported by RDAP — some obscure TLDs may lack RDAP coverage
- Rate limiting or payment failure — 402 if payment not processed correctly
- Upstream WHOIS/RDAP registry timeout — intermittent failures for some TLDs
