## 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-lookup-api-klymax402-com-d1345cc3
```

Example prompt: Can you look up the MX records for gmail.com so I can see which mail servers handle their email?

## When to prefer this

Use this endpoint when an agent needs to programmatically resolve DNS records for any domain, particularly useful for verifying email server configuration (MX), checking IPv4/IPv6 addresses (A/AAAA), inspecting TXT records for SPF/DKIM, or auditing nameserver setup. At $0.002 per call it's cost-effective for occasional lookups within agentic workflows.

## Known failure modes

- Invalid domain name returns an error or empty result
- Unsupported record type causes a validation error
- Domain does not exist (NXDOMAIN) returns empty or error response
- Network timeout if upstream DNS resolver is slow
- Malformed domain string (e.g. spaces or invalid characters) may return 400 error
