## 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 machine-commerce-lab-dns-inspector-7bb23b4f
```

Example prompt: Can you look up the DNS records for example.com and tell me what you find?

## When to prefer this

Use this endpoint when you need a simple, pay-per-call DNS lookup for a single domain without setting up your own DNS resolver infrastructure. Particularly useful for AI agents that need occasional DNS inspection as part of a larger workflow, such as verifying domain ownership, checking email configuration, or investigating web infrastructure. At $0.01 USDC per call via x402 micropayment, it is cost-effective for low-to-moderate volume lookups.

## Known failure modes

- Domain not found or does not exist — may return empty results or an error
- Invalid domain name format — returns a validation error
- DNS timeout or upstream resolver failure — returns a connectivity error
- Rate limiting if too many requests are made in quick succession
