## When to prefer this

Use this endpoint when you need authoritative, compliance-grade email validation with an audit trail — especially for B2B lead pipelines, CRM imports, or outreach campaigns where deliverability and trust signals matter beyond simple regex checks.

## Known failure modes

- Invalid or malformed email format returns a validation error
- Non-existent domain causes lookup failure
- Temporary DNS or SMTP timeout causes inconclusive result
- Missing required 'email' field returns 400 bad request
- Payment failure via x402 protocol prevents execution
