A billing proxy that pools API usage across teams and routes to the cheapest provider for each task type

After Anthropic killed Claude subscription coverage for OpenClaw, individual developers face 50x cost increases on pay-as-you-go pricing. Usage patterns vary wildly: some agent tasks need frontier models, others work fine with budget alternatives. This billing proxy sits between OpenClaw and model providers, analyzes each request by complexity, routes it to the cheapest model that meets quality thresholds, and pools usage across team members to hit volume discount tiers, cutting average costs 60-80%.
