The unit rate applies when a result is found. You pay only for results. A run that finds nothing, fails or ends with an unconfirmed outcome is not charged, and the hold comes back in full; Ahel covers what the provider billed. A run that stops partway charges for the rows it delivered, or for the whole call when the provider bills by the call. Pending charges stay held until the provider settles.
