• Credential chain auth — OAuth PKCE flow + API key auth with automatic discovery
• Provider catalog — discover available providers, models, and subscription tiers
• Usage tracking — real-time usage counters with near-limit detection and fallback triggers
• Multi-account subscriptions — aggregate capacity across multiple accounts on the same provider
• Audit logging — structured, redactable audit trail with configurable persistence
