Technology Deep Dive — Section 14

Transparent Billing

Pay only for what you use. Every token metered per model, per project, per user. No surprise bills. No hidden fees. Hard stop at zero balance.

Pre-paid credits Per-model metering Auto top-up

Pre-Paid Credit Wallet

Your organisation loads credits before use. Every AI operation deducts from your wallet in real time. When credits hit zero, operations stop cleanly — no runaway costs, no month-end surprises.

Hard Stop
Operations pause cleanly at zero balance — no overruns

Per-Model Metering

Every token is tracked by model, project, user, and agent. You always know exactly which AI model costs what. The dual-write architecture ensures your internal balance and Stripe invoices always agree.

claude-haiku-4-5 28,900 $0.029 Marv

Auto Top-Up

Your agents never stop mid-task because of low credits. Configure a threshold and top-up amount — when your balance drops below the threshold, credits are automatically added. Built-in safety limits prevent runaway charges.
