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.

Dashboard: https://openrouter.ezsite.ai

Quick Setup

1. Sign up at https://openrouter.ezsite.ai
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

Base URLs

| Provider | Base URL | Use With |

|----------|----------|----------|

| Claude / Anthropic | https://openrouter.ezsite.ai/api/claude | Claude Code, Anthropic SDK |

| OpenAI | https://openrouter.ezsite.ai/api/openai/v1 | Cursor, OpenAI SDK, ChatGPT-compatible tools |

| Gemini | https://openrouter.ezsite.ai/api/gemini | Gemini SDK, Google AI tools |
