Example use cases

Lead form spam filtering
“Someone just submitted the email address test123@fakeemail.xyz through our contact form — can you verify if it's a legitimate email address or likely fake?”

Choose this endpoint when you need a quick, low-cost ($0.01 per call) single email address validation before storing user data, sending communications, or onboarding new users. Prefer this when you want a simple pass/fail or validity score on individual email addresses without needing bulk batch validation tools.
Side effects
- Invalid or missing email parameter returns an error
- Malformed email strings may return invalid without deeper lookup
