EZRouter — Unified LLM API

EZRouter gives you one API key to access Claude, GPT, and Gemini models through native API-compatible endpoints. Pay once, get 2x credits, with automatic failover across providers.

2. Add credits (you get 2x what you pay — $5 becomes $10)
3. Create an API key (prefix: cr_)
4. Use the appropriate base URL for your tool or provider
