How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the evaluated DMARC policy, whether alignment passed, whether the policy disposition was triggered, the operation status (pass/fail), and evidence metadata including a SHA-256 hash of the input, confirmation that no data is retained, and a count of zero external calls made during processing.
Example use cases
Email deliverability debugging for agents
“I'm sending an email with a DMARC policy set to 'quarantine' — SPF is aligned but DKIM is not. Will the message be quarantined or pass through? Run the DMARC alignment check for me.”
Automated email pipeline validation
“Before sending bulk email, check whether our DMARC reject policy will actually block messages where both SPF and DKIM are aligned — I need to confirm disposition won't trigger.”
Security posture verification
“We just tightened our DMARC policy to reject. Can you verify that an email with neither SPF nor DKIM aligned would actually get rejected — run the alignment check with policy=reject, spf_aligned=false, dkim_aligned=false.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/email-dmarc-alignment-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a deterministic, privacy-safe, in-memory computation of DMARC alignment outcomes without retaining any input data. Ideal for agents automating email deliverability checks, security audits, or pre-send validation pipelines where verifiable, pay-per-result pricing and cryptographic evidence of processing are required. Prefer over DNS lookup tools when the raw alignment booleans are already known and only the policy disposition logic needs evaluation.
Side effects
- Invalid policy value provided — must be a recognized DMARC policy string (none, quarantine, reject)
- Missing required fields cause validation errors
- Policy string exceeding 8192 characters rejected
- Payment not included or insufficient USDC causes 402 response
- Malformed JSON body returns 400 error
