Frequently asked questions
Are unknown API results free?
Yes—QuickEmailVerification does not deduct credits when it returns an unknown result.
What is the difference between persistent and per-day credits?
Persistent credits are one-time purchases that never expire. Per-day credits come from a monthly subscription, reset each day, and are consumed before persistent credits kick in as backup.
How fast is the API?
Most single verification requests complete in under 1.2 seconds according to QEV documentation.
