Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 24k-labs-dns-lookup-47a8e150 -d '<json body>'
```

Example prompt: Can you look up the DNS records for api.example.com and tell me what IP addresses it resolves to?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call DNS resolution without standing up your own DNS resolver infrastructure, or when operating in an x402-enabled micropayment workflow and need DNS lookup as part of an automated agent pipeline.

## Known failure modes

- Non-existent domain returns empty answers array
- Invalid hostname format may return an error
- DNS query timeout for slow or unreachable nameservers
- NXDOMAIN responses for unregistered domains
