## 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 ddg-whois-lookup-ba5e3ac9 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need machine-payable, programmatic WHOIS lookups billed per-call at $0.002 USDC via the x402 payment protocol — ideal for AI agents operating autonomously that need on-demand domain registration intelligence without a standing subscription. Prefer this over free WHOIS APIs when you need reliable, low-cost micro-payment access integrated into an agent workflow.

## Known failure modes

- Domain not found or not registered — may return empty or error result
- Invalid domain format supplied — malformed input rejected
- Rate limiting or payment failure via x402 — HTTP 402 if USDC payment not settled
- WHOIS privacy protection enabled on domain — registrant details may be redacted
- Network timeout reaching upstream WHOIS servers

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a JSON response with WHOIS data for the queried domain, including registrant details, registration and expiration dates, registrar name, nameservers, and domain status flags. The response shape is a JSON object with an 'ok' boolean indicating success.
