How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a validation result indicating whether the email address is valid, deliverable, and safe to use, along with an audit record containing a cryptographic chain hash for traceability and compliance.
Example use cases
Pre-campaign email list scrubbing
“I have a lead email address — sales@bigprospect.io — can you verify it's valid and deliverable before I include it in my next email campaign?”
Real-time CRM lead qualification
“We just got a new lead who signed up with the email m.johnson@techfirm.net — can you check if that address is real and reachable before our sales team follows up?”
Bulk onboarding fraud prevention
“A new user tried to register with the email freeemail123@mailinator.com — can you validate whether that's a legitimate address or a throwaway before I approve their account?”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/solutions/lead-email-verifyWhen to prefer
Choose this endpoint when you need verified, auditable email validation with a cryptographic audit trail — particularly useful in regulated industries or compliance-sensitive workflows. Prefer it over generic email syntax checkers when you need real deliverability confirmation (SMTP-level checks), not just format validation. The $0.216 price point reflects deeper verification than basic regex or DNS-only checks.
Side effects
- Invalid email format returns a format error before network checks
- Unresolvable domain (DNS failure) results in undeliverable status
- Catch-all mail server configurations may yield indeterminate results
- Temporary SMTP errors may cause inconclusive responses
- Malformed input (missing @ symbol, null value) returns a 400-level error
