What you are paying for
Addresses under watch, not queries. An address costs the same whether it is re-checked once a month or every hour, and looking one up is free on every plan and with no account at all. Screening a counterparty before a transfer should never be the thing a team rations.
The same address monitored across several EVM networks counts once. Only successful checks count — an invalid address, a rejected batch or an error on our side never consumes anything.
Going over your plan does not switch the service off. There is no automatic cutoff and no automatic overage charge; consistently over means a conversation about the right plan, not a locked account.
