## 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 speer-cyber-defense-domain-age-lookup-0776a6bf
```

Example prompt: Can you check how old the domain phishing-site-example.com is? I want to know if it was recently registered, which might indicate it's suspicious.

## When to prefer this

Use this endpoint when you need to assess whether a domain is newly registered as part of phishing detection, threat intelligence, or security investigations. Particularly useful for identifying newly created domains that are commonly used in phishing campaigns and fraud. Prefer this over generic WHOIS tools when you need a pay-per-call cybersecurity-focused analysis with no subscription required.

## Known failure modes

- HTTP 503 if the security analysis fails (not billed)
- Missing or invalid domain query parameter returns error
- Domain not found in registration databases
- Rate limiting or payment failure via x402 protocol
