## 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 dns-txt-dmarc-report-record-lookup-14ae8e43 -d '<json body>'
```

Example prompt: Can you fetch the raw DNS TXT record at _report._dmarc for example.com so I can see where DMARC reports are being sent?

## When to prefer this

Use this endpoint when you need the raw, unfiltered _report._dmarc TXT record for a domain and are ready to pay per call. If a free sandbox equivalent (POST /v1/sandbox/dns-txt-dmarc-report) is available, prefer that first to avoid charges.

## Known failure modes

- Hostname does not exist or has no _report._dmarc TXT record — returns empty or error response
- Malformed hostname input exceeding 253 characters — validation error
- DNS resolution timeout or upstream DNS failure — returns error
- Payment of $0.008 USDC not provided — 402 Payment Required response

## How this service works

Call when an agent needs TXT at _report._dmarc, unfiltered. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dmarc-report first.

## Output

Returns the raw, unfiltered content of the DNS TXT record located at _report._dmarc.<hostname>, which typically contains DMARC external reporting authorization entries.
