How this service works
CommsHarbor: email security audit of a domain (SPF, DKIM, DMARC, MX and a score), paid per call
Output
Returns the results of SPF, DKIM, DMARC, and MX record checks for the requested domain along with an aggregated email security score, indicating which email authentication standards are properly configured, missing, or misconfigured.
Example use cases
Pre-campaign deliverability check
“Before I send out my email newsletter, can you audit the email security setup for morningbloom.co — I want to make sure SPF, DKIM, and DMARC are all properly configured so my emails don't land in spam?”
Vendor security due diligence
“I'm vetting a new vendor and I want to know how seriously they take email security — can you check the email authentication records for acmecorp.io and give me a score?”
Diagnosing email spoofing risk
“Someone told me our domain techstartup.ai might be vulnerable to email spoofing — can you audit the SPF, DKIM, and DMARC records and tell me where we stand?”

Endpoint
GEThttps://commsharbor.com/api/x402/email-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call email security posture check covering all four major email authentication standards (SPF, DKIM, DMARC, MX) with an aggregated score, especially in agentic workflows where you want to avoid subscription overhead and just pay $0.01 per domain checked.
Side effects
- Invalid or non-existent domain returns an error or empty results
- Subdomain input is automatically reduced to the registrable domain, which may differ from user expectation
- DNS lookup failures for domains with propagation issues may return incomplete results
- Payment not processed results in HTTP 402 rejection before the check runs
