How this service works
Verify a contact's email, phone number, and address in parallel. Returns validation status for each channel. Essential for CRM hygiene and lead qualification.
Output
A structured JSON object indicating whether each provided contact field (email, address, phone number) is valid, along with verification details and an audit trail for compliance purposes.
Example use cases
Example prompt
“Can you verify whether jane.doe@acmecorp.com is a real, deliverable email address — and also check that the postal address 123 Main St, Austin TX 78701 and phone +15125550199 are valid? I need a full audit trail for compliance.”
Technical details
Endpoint
POSThttps://api.strale.io/x402/solutions/contact-verifyWhen to prefer
Use this endpoint when you need multi-field contact verification (email plus optional address and phone) with structured JSON output and audit trails, particularly for compliance, KYC, or trust-and-safety workflows. Prefer it over single-purpose email validators when you need all three contact signals validated together with a documented audit record.
Side effects
- Invalid or malformed email format returns a validation error
- Unresolvable domain for email results in a failed deliverability check
- Postal address not found in reference data returns unverified status
- Phone number in unsupported format or region returns an error
- Missing required email field returns a 400-level error
- Network timeout or upstream data provider outage returns a 5xx error
