How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with status 'ok' and a data payload containing SPF and DMARC audit findings for the queried email/domain, along with an roi_proof field indicating compression ratio (e.g. 91.4%) reflecting how efficiently the result was distilled.
Example use cases
Pre-send email deliverability check
“Before I launch this email campaign, can you check whether marketing@mybrand.com has valid SPF and DMARC records so I know my emails won't get flagged as spam?”
Anti-spoofing security audit
“I'm worried someone could spoof our company email — can you audit the SPF and DMARC settings for admin@acmecorp.com and tell me if we're protected?”
New domain email setup verification
“I just set up a new domain and configured SPF and DMARC in DNS — can you check hello@newstartup.io to confirm everything looks correct before I start sending emails?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/spf-dmarc-auditor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.005 USDC) programmatic audit of SPF and DMARC DNS records for a specific email address or domain. It is well-suited for AI agent workflows that need to validate email authentication as part of a larger pipeline, especially when paying per-call via x402 on Base is acceptable and you want a distilled, agent-friendly JSON response rather than a verbose raw DNS dump.
Side effects
- Missing required 'input' parameter returns validation error
- Invalid or non-existent email/domain returns empty or error data
- DNS lookup timeout if domain nameservers are slow
- Malformed email address format may cause query failure
- Payment failure via x402/USDC prevents request from being processed
