Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 lookproof-dns-txt-verification-token-listing-15b3526b
```

Example prompt: Can you pull all the third-party verification tokens sitting in the TXT records for acmecorp.com — I want to see every service like Google, Microsoft, Stripe, DocuSign and others that have a domain ownership claim there so I can audit and clean up any stale ones.

## When to prefer this

Use this endpoint when you need to enumerate, audit, or clean up third-party domain ownership verification tokens in apex TXT records. It is the right choice when the goal is to discover which external services (Google, Microsoft, Stripe, DocuSign, etc.) have verified a domain, particularly before DNS migrations, post-acquisition reviews, or compliance audits. Prefer this over generic DNS lookup tools when you specifically want structured, service-identified verification token data rather than raw TXT record strings.

## Known failure modes

- Domain not found or does not exist — returns empty result or error
- Domain has no TXT records — returns empty token list
- Unrecognized or non-standard verification token formats not in the fixed list are silently ignored
- Network timeout or DNS resolution failure
- Invalid domain format supplied in query parameter

## How this service works

Check SPF, DMARC, DKIM, MTA-STS, DNSSEC and more, with results that explain what was found and why. Free browser checks and a pay-per-request API with x402.

## Output

A structured list of domain verification tokens found in the domain's apex TXT records, each entry including the full public token value, the service it belongs to (e.g. Google, Microsoft, Atlassian, Facebook, Apple, Adobe, DocuSign, Stripe), and any additional context for services with multiple tokens — drawn from a fixed, versioned reference list.
