Abstract Email Reputation Check

Use this endpoint when you need a quick, real-time reputation and risk score for a single email address — ideal for fraud prevention at signup, lead qualification, or filtering low-quality or disposable emails before sending campaigns. Prefer this over basic email syntax validators when you need behavioral and reputation signals, not just format checks.

• Invalid or malformed email address returns a validation error
• Missing required 'email' field returns a 400 Bad Request
• Unrecognized or brand new email domain may yield low-confidence scores
• Rate limit exceeded returns a 429 error
• Network timeout or upstream API unavailability returns a 503 error
