## 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 24k-labs-dns-lookup-0f255a7f -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need programmatic, structured DNS record resolution without running your own DNS resolver or managing DoH infrastructure. It is well-suited for agents that need to verify email configuration (MX/TXT/SPF), check domain-to-IP mappings, audit nameserver delegations, or validate DNS propagation. Prefer this over generic HTTP-based domain lookup tools when you specifically need DNS record data for multiple record types.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns error or empty record set
- Unsupported record type requested — may return an error or empty result
- DNS resolution timeout — upstream Google DoH unreachable
- Invalid domain name format — returns validation error
- Record type has no entries for the domain — returns empty result

## How this service works

Resolve A/AAAA/MX/TXT/NS/CNAME records for a domain over DNS-over-HTTPS (Google).

## Output

Returns the resolved DNS records for the queried domain and record type, including values such as IP addresses (A/AAAA), mail server hostnames and priorities (MX), canonical names (CNAME), name server hostnames (NS), and raw text values (TXT), sourced via Google DNS-over-HTTPS.
