How this service works
Pay-per-call machine utilities for autonomous agents.
Output
Returns structured machine-readable risk indicators for the submitted email address, including: syntax validity assessment, domain existence and MX record status, SPF and DMARC policy presence, a flag for whether the domain is a known disposable/temporary email provider, and a flag for whether the local part is a generic role account (e.g. info@, admin@, support@).
Example use cases
Screening signups for disposable emails
“Before I approve this new user registration, can you check whether 'freestuff99@guerrillamail.com' is a disposable or throwaway email address and flag any other risk signals?”
Fraud check on payment email
“A transaction just came in from 'billing@mailinator.com' — can you analyze that email for fraud risk signals, including whether the domain has real MX records and passes SPF and DMARC checks?”
Validating B2B outreach list
“I'm about to send a campaign to 'info@acmecorp.io' — can you check if that's a role account and whether the domain's email infrastructure looks legitimate before I add it to my list?”
Technical details
Endpoint
POSThttps://agent-vending-production.up.railway.app/v1/email-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal email risk assessment in a single call — covering syntax, DNS infrastructure (MX, SPF, DMARC), disposable domain detection, and role-account classification. It is ideal for agent-driven onboarding flows, fraud screening, or outreach validation where you need structured, machine-readable risk data rather than a simple boolean valid/invalid check.
Side effects
- Invalid or malformed email string returns a syntax error or validation failure
- Non-existent domain with no DNS records may result in failed MX/SPF lookups
- Timeout or connectivity issues reaching DNS resolvers may yield incomplete signals
- Very new domains may not yet have SPF/DMARC records, producing false negatives
- Private or internal email domains may not resolve from public DNS
