# dns.agentutil.net DNS Lookup

> dns.agentutil.net DNS Lookup is a paid API for AI agents from dns.agentutil.net, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Performs DNS record lookups for a given domain, returning records of a specified type (A, AAAA, MX, TXT, CNAME, NS, SOA, or ANY)

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-agentutil-net-94d40fce -d '<json body>'
```

Example prompt: What are the MX records for gmail.com? I want to see what mail servers it's using.

## When to prefer this

Use this endpoint when an agent needs to programmatically resolve DNS records for a domain — such as verifying email server configuration, checking domain ownership via TXT records, resolving hostnames to IPs, or auditing nameserver delegation. Priced at $0.001 per call, it is suitable for on-demand lookups in automated workflows.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns error or empty result
- Invalid domain name format — returns validation error
- Unsupported record type — rejected by enum validation
- DNS resolution timeout — upstream resolver unavailable
- Payment failure — x402 payment not accepted or insufficient funds
