## 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 txt-record-lookup-for-dns-verification-and-mail-policy-79ddeb15 -d '<json body>'

Example prompt: Can you look up the DNS TXT records for acmecorp.com so I can see its SPF, DMARC, and any domain verification tokens?

## When to prefer this

Use this endpoint when you need raw DNS TXT records for a domain — particularly for auditing SPF, DKIM, DMARC, or domain verification tokens. Prefer this over broader DNS lookup tools when the specific use case is mail authentication policy review or verifying domain ownership tokens for sales and marketing operations.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns empty or error response
- Domain has no TXT records published — returns empty list
- Invalid domain format provided — returns validation error
- DNS timeout or resolver failure — returns error
- Private/internal domain not resolvable from public DNS — returns no results

## How this service works

TXT record lookup for Sales operations: Return TXT records used for verification and mail policy. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns all DNS TXT records associated with the queried domain, including SPF entries (v=spf1...), DMARC policies (_dmarc), domain verification tokens (e.g. google-site-verification, MS=ms...), and any other TXT record strings published in DNS for that domain.
