 ## Overview
 
 Sub2API is an AI API gateway platform designed to distribute and manage API quotas from AI product subscriptions (like Claude Code $200/month). Users can access upstream AI services through platform-generated API Keys, while the platform handles authentication, billing, load balancing, and request forwarding.
