## 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 revnuvo-domain-verification-api-fa47fb11 -d '<json body>'
```

Example prompt: Can you check whether acmecorp.io is a real, active domain — does it have DNS A records, MX records for email, and is DNSSEC enabled?

## When to prefer this

Choose this endpoint when you need a quick, low-cost DNS and domain trust check — particularly when you want to verify both DNS resolution (A records) and email capability (MX records) alongside DNSSEC status in a single call. It is well-suited for AI agents doing lightweight due diligence on domains encountered in user-submitted data, emails, or onboarding flows, and pays per-call via USDC x402 with no subscription required.

## Known failure modes

- Invalid or malformed domain input — returns validation error
- Domain does not exist — exists: false with other fields false
- Network/DNS resolver timeout — may return error or partial results
- Missing required 'domain' field — returns 400-level error
- Payment failure via x402 — request blocked before processing

## How this service works

Domain verification, DNS lookup, and trust assessment for AI agents and developers. x402 USDC payments on Base.

## Output

Returns a JSON object with the queried domain name, a boolean indicating whether the domain exists, whether it has an A record (has_a), whether it has MX records (has_mx), whether DNSSEC is enabled (dnssec), and the ISO 8601 timestamp of when the check was performed.
