From per-token pricing to provisioned throughput — how nRouter tracks costs across every major LLM provider with a credit-based system.
How to attribute LLM costs across multi-agent systems: virtual keys per agent role, per-run cost accumulation, budget enforcement, and the observability patterns that prevent surprise bills.
