## 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`):

Example prompt: Can you look up the DKIM selector 'google' under _domainkey for the domain acmecorp.com and tell me what DNS record it returns?

## When to prefer this

Use this endpoint when you need a quick, cheap DNS-level check of a DKIM selector record for a specific domain and selector name. Prefer it over full email validation services when you only need raw DNS data — not inbox verification or end-to-end email deliverability testing.

## Known failure modes

- Selector or domain not found in DNS — record may not exist or may not yet have propagated
- Invalid domain format causing lookup failure
- DNS timeout or transient resolution error
- Selector exists but TXT record is malformed or empty
