## 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-record-lookup-94dab585
```

Example prompt: What are the A records for github.com? Can you do a DNS lookup for me?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call DNS resolution without managing your own resolver infrastructure. Prefer it for lightweight agent workflows that need to programmatically check DNS records for one or a few hostnames on demand. It is well-suited for validation, enrichment, or investigation tasks where standing up a full DNS library is overkill.

## Known failure modes

- Hostname does not exist or is not resolvable — returns empty or NXDOMAIN equivalent
- Invalid record type specified — may return error or default to A record
- Network timeout reaching DNS resolver — returns timeout error
- Missing required 'name' query parameter — returns validation error
- Rate limiting or payment failure — returns 402 or 429 status

## How this service works

DNS, WHOIS/RDAP, IP ownership and one-call domain reports.

## Output

A JSON response containing the resolved DNS records for the queried hostname, including record type, values (e.g. IP addresses, hostnames, priorities), and TTL information where available.
