## 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 fitze-x402-seller-domain-intelligence-c3cefb24 -d '<json body>'
```

Example prompt: Can you vet the domain mysterysupplier.io for me — I want to see its DNS records, who registered it and when it expires, and how many SSL certificates have been issued for it?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.02), no-signup domain vetting call that bundles DNS, RDAP registration metadata, and certificate transparency history in a single response. It is ideal for fraud detection pipelines, vendor due-diligence agents, and security triage workflows where you want correlated domain signals without stitching together multiple APIs. Prefer alternatives if you need bulk/batch domain lookups, WHOIS full-text output, real-time threat-intelligence feeds, or geolocation of the domain's IPs.

## Known failure modes

- Domain does not exist or has never been registered — RDAP and DNS fields may be empty or null
- Domain is under RDAP privacy/redaction — registrar details may be incomplete
- crt.sh lookup fails or returns no results for a newly registered or obscure domain
- Invalid domain format supplied — validation error returned
- Upstream DNS resolver or RDAP registry is temporarily unavailable — partial results or timeout

## How this service works

Pay-per-call AI/data tools settled in USDC on Base via x402. No account, no API key — pay the 402 and receive the result. All endpoints also accept a bare hostname without the https:// prefix.

## Output

Returns a JSON object with: DNS records (A, MX, NS, TXT), RDAP data (registrar name, creation date, expiry date, status flags), the queried domain string, and certificate transparency data from crt.sh (total certificate count, earliest issuance date, latest issuance date).
