# Revnuvo DNS Lookup & Domain Verification

> Revnuvo DNS Lookup & Domain Verification is a paid API for AI agents from resource.revnuvo.site, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Performs a full DNS record lookup (A, AAAA, MX, NS, TXT, CNAME) for a given domain, enabling domain verification and trust assessment.

## 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-dns-lookup-domain-verification-dbaf5b80 -d '<json body>'
```

Example prompt: Can you do a full DNS lookup on openai.com and show me all its A, MX, NS, and TXT records so I can verify how it's configured?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-record-type DNS lookup in a single call and are operating in an x402 micropayment environment on Base. It is well-suited for AI agents performing domain trust assessments, email deliverability checks, or infrastructure audits where all standard DNS record types are needed simultaneously rather than querying a public resolver manually.

## Known failure modes

- Domain does not exist (NXDOMAIN) — may return empty record arrays or an error response
- Malformed domain input — missing or invalid domain string returns a validation error
- DNS timeout — upstream resolver may fail for unreachable or misconfigured domains
- Payment failure — x402 USDC payment not processed, request rejected before execution

## 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 containing the domain name, arrays of DNS records by type (A, AAAA, MX, NS, TXT, CNAME), and a resolved_at timestamp indicating when the lookup was performed. Empty arrays indicate no records of that type exist.
