Example prompt: Can you pull the TXT records for example.com so I can check what SPF, DMARC, and domain verification entries are configured?

## When to prefer this

Use this endpoint when you need to inspect the DNS TXT records of a public domain for email-related purposes such as auditing SPF/DMARC/DKIM configuration, checking domain ownership verification tokens, or validating email security posture. It is a lightweight, read-only DNS query that is fast and cheap ($0.01 USDC). Prefer this over manual DNS tools when building automated email deliverability checks, domain onboarding workflows, or security audits inside an AI agent pipeline.

## Known failure modes

- Domain does not exist in DNS — returns empty or NXDOMAIN-equivalent response
- Domain has no TXT records configured — returns empty array
- Malformed domain input — may return an error or empty result
- DNS resolution timeout — transient failure for unreachable DNS servers
- Private or internal domains not resolvable via public DNS
