## 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-security-review-13188c1b -d '<json body>'
```

Example prompt: Can you pull the DNS TXT records for stripe.com so I can review its SPF, DMARC, and any domain verification tokens?

## When to prefer this

Use this endpoint when you need to inspect a domain's DNS TXT records specifically for security review purposes — checking SPF, DKIM, DMARC mail policies, or domain verification tokens. Prefer this over a general DNS lookup tool when the goal is security auditing of email infrastructure or domain ownership proof, and you only need TXT record data without broader DNS record types (A, MX, NS, etc.).

## Known failure modes

- Domain does not exist (NXDOMAIN) — no records returned
- Domain exists but has no TXT records — empty result set
- Malformed domain input — validation error
- DNS resolution timeout — transient network failure
- Private/internal domain not resolvable from public DNS — no data returned

## How this service works

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

## Output

Returns the set of TXT records published in DNS for the queried domain, including SPF (v=spf1...), DMARC (_dmarc), DKIM selectors, and any domain ownership verification strings from providers like Google, Microsoft, or others. No email is sent and no inbox is verified — purely DNS data.
