Get the account lead balance and tier. The unit is a lead: 1 lead = 1 new business found by a search, with enrichment, relevance check, verified address and the monthly re-check included. Businesses you already hold: enrichment is five per lead, enrolling in the monthly re-check is two per lead. Named contacts found on the open web cost 2 leads each, charged only when a person is found. Email verification is included at no charge. Unused leads roll over, up to three months' allowance.
