## 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 dns-intelligence-api-72a1e344 -d '<json body>'
```

Example prompt: Can you pull all the DNS records for payapi.market — I want to see the A, MX, NS, TXT, and CNAME entries, plus any subdomain and WHOIS info you can find?

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one DNS intelligence snapshot for a domain in a single call, especially when you want DNS records alongside WHOIS, SSL, subdomain, and reverse-IP data together. Ideal for security research, infrastructure auditing, email troubleshooting, and domain due diligence workflows where breadth of DNS context matters.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns empty or null record sets
- Invalid domain format — API may return a validation error
- Payment failure via x402 — request not processed if USDC payment is rejected
- DNS timeout or upstream resolver failure — partial or missing records
- Domains with strict privacy protection may return limited WHOIS data
