## 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

```

Example prompt: Can you do a WHOIS/RDAP lookup on example.com and tell me who registered it, when it was created, and what nameservers it's using?

## When to prefer this

Choose this endpoint when you need pay-per-call WHOIS/RDAP lookups without a subscription, especially in agentic workflows where domain intelligence is needed on-demand and settled via USDC micropayments on Base via x402. Prefer it over traditional WHOIS APIs when operating in a crypto-native or x402-compatible payment environment.

## Known failure modes

- Domain not found or unregistered — empty or 404-style RDAP response
- Invalid domain or IP format — malformed query parameter rejected
- RDAP registry unavailable for TLD — upstream timeout or error
- Payment not settled — x402 payment required error before data is returned
- Rate limit exceeded — too many requests in a short window

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns RDAP/WHOIS registration data for the queried domain or IP, including registrant details, registrar name, creation and expiration dates, nameservers, and domain status codes.
