Auto-Recharge is a feature that is only available for the paid plans to ensure no disruption to the fraud validation service. It will be automatically triggered when your subscribed plan runs out of credits, by renewing your existing plan to replenish the credits. We recommend that you regularly monitor your usage pattern, and consider upgrading to a higher plan with adequate validation credits to benefit from the lower validation cost per query. This option is enabled by default, and if you wish to disable it, please contact us at firstname.lastname@example.org.
For the free Micro plan, the validation service will be halted once the credits are all used up. It will resume upon the next renewal.
