## 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 yruz-dns-lookup-a4b7a2a9 -d '<json body>'
```

Example prompt: Look up all DNS records for example.com so I can see its current DNS configuration.

## When to prefer this

Use this endpoint when you need a quick, pay-per-use DNS lookup without setting up your own DNS resolver. Suitable for agents that occasionally need to resolve or audit DNS records for arbitrary domains without maintaining infrastructure. Costs $0.002 USDC per call, making it practical for low-volume or on-demand lookups.

## Known failure modes

- Domain does not exist — returns empty or NXDOMAIN result
- Invalid domain format — may return an error or empty result
- Unsupported record type string — may return empty result
- Network or resolver timeout — returns an error response
- Rate limit or payment failure — request rejected with 402
