The unit rate applies when a result is found. Misses are free when the provider does not bill them; provider-billed misses are charged at cost, without Ahel's margin. Provider-billed failures follow the quoted billing rules. A run that never reaches a provider is not charged. Pending charges stay held until the provider settles.

Quoted before it runs, paid from your prepaid balance. No top-up fee. Pay per call; each call’s price is shown before it runs. The provider ↓
