How this service works
Agent intents: verify signup email · is disposable? · check DMARC before outreach · role-account risk. One call returns syntax, MX, SPF, DKIM, DMARC, disposable, role, provider, score 0-100 (<300ms). x402 on Base for AI agents.
Output
Returns a structured response containing: syntax validity, MX record presence and validity, SPF record status, DKIM record status, DMARC policy status, a boolean flag for disposable/temporary email providers, a boolean flag for role-based addresses (e.g. info@, admin@), the detected email provider name, and a numeric delivery score from 0 to 100 — all returned in under 300ms.
Example use cases
Pre-send email list hygiene
“Before I send this campaign, check whether the email address sarah.johnson@acmecorp.com is actually deliverable and tell me if it's a disposable address or a role account.”
Signup form fraud prevention
“A user just signed up with the email throwaway123@mailnull.com — can you check if it's a disposable or fake address and give me a deliverability score so I can decide whether to accept the registration?”
Cold outreach quality check
“I'm about to cold-email prospects and want to verify that contact@bigclient.io has valid MX records, passes SPF and DMARC, and has a high enough delivery score to be worth including.”
Technical details
Endpoint
POSThttps://emailiq.dev/email/intelligence?utm_source=zero.xyzWhen to prefer
Choose EmailIQ when you need a fast, comprehensive single-call email intelligence check that covers not just syntax but the full deliverability stack — MX, SPF, DKIM, DMARC, disposable detection, role detection, and a numeric score — all in under 300ms. Ideal when you need to make real-time decisions at signup or before sending, and want one score to summarize deliverability risk rather than stitching together multiple checks.
Side effects
- Invalid or malformed email address returns a syntax error or low-confidence result
- Unknown or newly registered domains may not have MX/SPF/DMARC records detectable in time
- Temporary DNS propagation delays can cause false negatives on MX lookups
- Rate limiting or payment failure may result in 402 or 429 responses
- Extremely long email addresses (over 320 characters) are rejected
