## 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 x402-fatihai-app-31b10b59
```

Example prompt: Look up all the DNS records for github.com — I want to see its A, AAAA, MX, TXT, and NS records.

## When to prefer this

Use this endpoint when you need to quickly retrieve multiple DNS record types (A, AAAA, MX, TXT, NS) for a domain in a single call, especially in automated workflows involving email verification, domain validation, infrastructure checks, or network diagnostics. It charges a small per-call fee via x402 and is suited for on-demand lookups rather than bulk batch operations.

## Known failure modes

- Domain does not exist or is not resolvable — returns empty or error response
- Invalid domain name format — may return a validation error
- DNS lookup timeout for slow or unresponsive nameservers
- Network errors from the upstream DNS resolver

## How this service works

DNS record lookup for any domain. Returns A, AAAA, MX, TXT, NS records.

## Output

Returns DNS records for the queried domain, including A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail exchange), TXT (text/verification records), and NS (nameserver) records.
