How this service works
Email DMARC Alignment Check: Email DMARC Alignment Check combines caller-supplied SPF and DKIM alignment outcomes for DMARC from bounded caller-supplied values without an external provider. Call Email DMARC Alignment Check before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Email DMARC Alignment Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on B…
Output
Returns versioned deterministic JSON containing normalized evidence of the supplied inputs, the computed DMARC alignment finding, and an explicit pass or advisory status indicating whether the email satisfies the given DMARC policy.
Example use cases
Email gateway pre-acceptance check
“Before my mail server accepts this inbound email, run a DMARC alignment check: the policy is 'quarantine', SPF alignment is true, and DKIM alignment is false — does it pass?”
Email authentication audit pipeline
“I'm auditing a batch of email authentication results. For this one: DMARC policy is 'reject', both SPF and DKIM are aligned — compute the DMARC outcome and give me the structured finding.”
DMARC policy testing during setup
“I'm testing my new DMARC policy set to 'none'. If SPF alignment is false and DKIM alignment is true, what would the DMARC result be? Run the alignment check for me.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/email-dmarc-alignment-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, in-memory DMARC alignment computation with no external DNS or third-party provider dependency. Ideal for email gateways, audit pipelines, and DMARC policy testing where reproducible, versioned JSON output is required and you already have SPF/DKIM alignment booleans computed upstream.
Side effects
- Invalid or missing 'policy' string may return a validation error
- Non-boolean values for spf_aligned or dkim_aligned will likely cause a schema error
- Malformed request body returns a 400-level error
- Payment not included or insufficient USDC results in 402 Payment Required
