## 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 ipv4-address-lookup-dns-a-record-e6b25ca9 -d '<json body>'
```

Example prompt: Can you look up the public IPv4 address for github.com — I need the DNS A records for it?

## When to prefer this

Use this endpoint when you need a quick, cheap DNS A record lookup for a single hostname without building your own DNS resolver. Ideal for IT administration tasks such as firewall whitelisting, network audits, outage diagnostics, or verifying where a domain currently points. Not suitable for email verification (no MX or inbox checking) or bulk DNS lookups.

## Known failure modes

- Domain does not exist (NXDOMAIN) — no A records returned
- Domain has no A records (e.g. only MX or CNAME records present)
- Invalid domain format provided — may return error or empty result
- Temporary DNS resolution failure due to upstream DNS unavailability
- Private or internal hostnames not resolvable via public DNS

## How this service works

IPv4 address lookup for IT administration: Return public A records for the hostname. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the public DNS A records for the queried domain, providing one or more IPv4 addresses that the hostname currently resolves to. No email verification or inbox checks are performed — purely DNS data.
