How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok'), a data object containing the SPF and DMARC audit findings for the queried email/domain, and an roi_proof field showing a compression ratio percentage (e.g. 91.4%) indicating how efficiently the information was summarized.
Example use cases
Pre-send email campaign audit
“Before I launch this email campaign, can you audit SPF and DMARC for marketing@mybrand.com to make sure our emails won't land in spam?”
Security review for new domain
“We just set up a new domain — can you check if support@newstartup.io has SPF and DMARC properly configured so we're protected against email spoofing?”
Deliverability troubleshooting
“Our transactional emails from noreply@shopexample.com are being marked as spam — can you audit the SPF and DMARC records to see what's misconfigured?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/spf-dmarc-auditor?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, automated SPF and DMARC validation for an email domain without setting up your own DNS lookup tooling. Ideal for agents conducting email security audits, pre-campaign deliverability checks, or compliance reviews. At $0.005 USDC per call it is cost-effective for per-domain spot checks. Prefer this over general DNS tools when you specifically need structured email authentication analysis with a clean pass/fail result.
Side effects
- Missing or invalid email query parameter returns an error or empty data
- Domain with no SPF or DMARC records returns audit result indicating absent records
- Malformed email address may result in lookup failure
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
- DNS lookup timeouts for slow or unreachable nameservers
