## 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 tokenguard-company-domain-brief-c5e080d4 -d '<json body>'
```

Example prompt: Can you pull a domain brief for uniswap.org — I want to know how old the domain is, who registered it, how many subdomains it has, and when it expires?

## When to prefer this

Choose this endpoint when you need a quick, structured domain intelligence profile for due diligence, phishing detection, or trust assessment — particularly in crypto/DeFi research workflows where domain age and certificate history signal legitimacy. Prefer this over raw WHOIS lookups when you need a normalized, agent-ready JSON response with maturity scoring.

## Known failure modes

- Invalid or unresolvable domain returns empty or error response
- Newly registered domains may have limited data (low subdomain count, few certificates)
- Private/reserved domains (e.g. example.com) may return placeholder registrar data
- URL or email inputs are accepted but reduced to bare domain before lookup — malformed inputs may fail
- Rate limits or payment failures via x402 micropayment protocol may block the call

## How this service works

One-call company and domain profile from public records: RDAP registration (age, registrar, status, expiry, nameservers) plus certificate-transparency history for infrastructure footprint and subdomain discovery, resolved into a new / established / mature maturity read. Domain-based lead qualification and counterparty vetting without a proprietary data licence.

## Output

A JSON object with the domain's maturity classification (e.g. 'mature'), registrar name, domain age in days, days until expiry, number of subdomains detected, number of SSL/TLS certificates seen, and any advisory notes.
