## 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 polyform-domain-whois-age-lookup-2b7e248c
```

Example prompt: How old is stripe.com and who registered it? I want to know the creation date, registrar, and nameservers.

## When to prefer this

Use this endpoint when you need fast, pay-per-call domain age and WHOIS metadata without creating an account or managing API keys. Ideal for agents performing one-off domain lookups for fraud detection, trust scoring, or competitive research. Prefer this over traditional WHOIS tools when operating in an autonomous agent context with x402 micropayment capability already set up.

## Known failure modes

- Domain not found in registry — returns empty or error response
- Invalid domain format — malformed input string rejected
- Payment failure — x402 micropayment not completed, call not fulfilled
- Rate or network timeout — transient infrastructure issue
- Newly registered domains may have propagation lag in WHOIS data

## How this service works

Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.

## Output

A JSON object containing the queried domain name, its age in days since registration, the ISO creation date string, the registrar name, and an array of nameserver hostnames.
