How this service works
Pay-per-call domain, email and website intelligence for AI agents (x402, USDC on Base). Free demos under /demo/<endpoint>.
Output
A JSON object containing: the normalized email address and its domain, a deliverability verdict (e.g. 'deliverable_likely'), boolean flags for SPF presence, MX record presence, syntax validity, disposable provider, role account, and free provider, plus the DMARC policy string for the domain.
Example use cases
Email list hygiene before campaign
“Before I send this marketing email, check if contact@acmecorp.com is actually deliverable — is it valid, does the domain have MX records, and is it a role account I should avoid?”
Detecting throwaway emails at signup
“A user just signed up with temp-mail123@mailinator.com — can you tell me if that's a disposable or throwaway email so I can decide whether to block the registration?”
B2B lead email verification
“I've got a lead with the email john.smith@hubspot.com — verify it for me: is it deliverable, does it have proper SPF and DMARC records, and is it a free provider or a real business domain?”
Technical details
Endpoint
GEThttps://domain-email-intel.laboutique.workers.dev/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, per-address email intelligence check with both syntax validation and live DNS record lookups (MX, SPF, DMARC) plus enrichment flags (disposable, role, free provider) in a single call — especially in agentic workflows that need to pay per-call via x402/USDC on Base rather than subscribing to a bulk email validation service.
Side effects
- Missing or malformed 'address' query parameter returns an error
- Unresolvable domain (DNS timeout) may result in hasMx: false with uncertain verdict
- Very new or obscure domains may return incomplete DMARC/SPF data
- Payment failure via x402/USDC will block the request before processing
