How credits work

Pay only for processed checks.

Email verification and unclassified domain checks use one credit. Known free and disposable provider checks are free.

Your balance stays yours.

Starter and purchased credits do not reset or expire. Add more only when you choose.

The public demo is separate.

No-key checks are limited to 10 per hour and never spend a project credit.
