Check one domain, free.
The same engine the paid audit runs, over one domain, returning what it actually found.
Request
GET https://guild.tradeuniquecapital.com/api/check?domain=example.com
Optionally add &ref=YOUR_CODE so the call is
attributed to you.
What you get back
- SPF record and whether it exceeds the RFC 7208 ten-lookup limit
- DMARC policy, and whether it enforces or only monitors
- Cross-domain DMARC reporting authorisation (RFC 7489 §7.1)
- MX and null-MX
- DKIM selectors found
- A posture grade, and how many checks completed
What it will not do
- Report a failed lookup as a finding — unknown is returned as unknown
- Serve as a scanner: 20 calls per caller per hour
- Read anything but public DNS
What the paid audit adds
- Up to five domains in one order
- DKIM probed across 34 known provider selectors
- Prioritised remediation with the exact records to publish
- A written report you can hand to whoever runs the DNS
