Example prompt: Can you pull all the DNS TXT records for acmesupplier.com so I can screen them as a vendor and check their SPF and DMARC policies?

## When to prefer this

Choose this endpoint when you need raw DNS TXT record data for a domain as part of vendor screening, third-party risk assessment, or email-authentication policy checks. It is a fast, low-cost read-only DNS lookup with no side effects. Prefer it over full email verification services when you only need the DNS-layer policy data (SPF, DMARC, DKIM) without testing live inbox delivery.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns empty result or DNS error
- Domain has no TXT records published — returns empty array
- Invalid domain format provided — may return validation error
- DNS resolution timeout — transient network failure
- Private or internal domains not resolvable via public DNS — no results returned

## How this service works

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

## Output

Returns an array of DNS TXT record strings for the queried domain, which may include SPF policies (v=spf1 ...), DMARC policies (_dmarc), DKIM selectors, domain verification tokens (e.g. Google or Microsoft site verification), and other arbitrary TXT entries. No email delivery or inbox verification is performed.
