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 verification result for each submitted contact field (email, phone, postal address), indicating validity status, deliverability, and any detected issues. Each response includes a cryptographic audit record with chain hashing for traceability and trust.
Example use cases
Pre-send email list hygiene
“Before I send this campaign, can you verify that sarah.jones@acmecorp.com is a real deliverable email address so I don't get bounces?”
Lead validation before CRM entry
“I just got a new lead with email m.chen@startup.io and phone +44-20-7946-0123 — can you verify both are legitimate before I add them to the CRM?”
Shipping address confirmation
“A customer entered '123 Elm Street, Springfield, IL 62701' as their shipping address — can you verify that address actually exists before we dispatch the order?”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/solutions/contact-verifyWhen to prefer
Choose this endpoint when you need a verifiable, auditable contact validation with a cryptographic trust record — especially in regulated industries, fraud prevention workflows, or agent pipelines where accountability matters. Prefer this over generic email-ping validators when you need multi-field contact verification (email + phone + address) in a single call with a tamper-evident audit trail across 27 countries.
Side effects
- Invalid or malformed email format returns a validation error
- Unresolvable or non-existent domain for email may return undeliverable status
- Phone number outside supported country format may fail format checking
- Postal address in unsupported country may not be verifiable
- Missing required email field returns a 400-level error
- Network or provider timeout returns a 5xx error
