PortaAIM
PortaAIM is an inference service delivery platform that combines PortaBilling with an AI gateway to authorize, meter, and settle AI usage in real time. It checks the customer, pricing rules, and balance before a request runs, reserves funds against the worst-case cost, then meters actual usage in tokens, images, audio, tool calls, or other units and releases any unused balance. Pricing, tokens, credits, and bundles are configured without code changes, and resellers are settled within the same system. PortaAIM routes requests to the lowest-cost capable model, offers a white-label customer portal, and runs across multiple sites for continuity. It supports full API and MCP access, and includes guardrail modules for frameworks such as the EU AI Act. Available as perpetual license or pay-as-you-go, self-hosted or hosted by PortaOne — built on 25+ years of real-time billing experience for nearly 500 operators worldwide.
