## Description

Quotio is a local LLM API proxy gateway and credential manager that intercepts and routes requests from command-line tools and integrated development environments to various AI model providers. It serves as a centralized authentication hub, managing API keys and service accounts to provide a unified interface for external AI agents.

The project distinguishes itself through a routing engine that implements priority-chain and round-robin load balancing to distribute workloads across multiple accounts. It features automated API key failover, which redirects requests to backup authentication keys when a primary provider returns rate limit or quota errors.

The system provides comprehensive monitoring and observability via a real-time dashboard that aggregates token consumption, costs, and success rates. It includes utilities for normalized usage tracking, account quota management, and resource monitoring specifically for IDEs. Security is handled through the use of the system-level encrypted keychain for credential storage and restricting proxy traffic to the local loopback address.
