Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you look up the MX records for gmail.com and tell me all the mail exchanger hosts and their priorities?

## When to prefer this

Choose this endpoint when you need fast, read-only DNS MX record lookups for a specific domain — especially for IT administration tasks like auditing mail routing, identifying email providers, or pre-flight checks before email migrations. It is not a substitute for SMTP connection testing, inbox verification, or sending email.

## Known failure modes

- Domain does not exist or has no MX records — returns empty list or DNS NXDOMAIN response
- Invalid domain format supplied — returns validation error
- DNS resolution timeout for the target domain — returns timeout error
- Private or internal domain not resolvable via public DNS — no results returned

## How this service works

Mail exchanger lookup for IT administration: Return the domain MX hosts and their delivery priorities. DNS data only; does not send email or verify that an inbox exists.

## Output

A list of MX (mail exchanger) records for the queried domain, each containing the hostname of the mail server and its associated priority integer. Lower priority numbers indicate preferred mail hosts. No email is sent and no inbox existence is verified — pure DNS data only.
