PortaAIM is a billing and monetization platform for AI services that connects usage tracking, pricing, cost monitoring, access control, and billing in one system. It supports two billing modes: full-fidelity billing, which authorizes each request against pricing, quotas, and balance before it runs, and pre-normalized billing, which prices and bills reported usage records after the fact. PortaAIM supports usage-based, token-based, subscription, prepaid credit, tiered, freemium, reseller, and outcome-based pricing models, which can be configured without code changes. It tracks vendor cost and customer revenue at the transaction level, providing real-time visibility into usage and profitability by customer, product, or account. PortaAIM is built by PortaOne, applying its telecom real-time billing experience to AI usage-based monetization.
