OpenRouter
A unified API that gives you access to 400+ AI models from dozens of providers through a single endpoint and API key.
What is OpenRouter?
OpenRouter is a platform that connects you to over 400 AI models from OpenAI, Anthropic, Google, Meta, and dozens of other providers through one API.
Instead of managing separate API keys and billing for each AI company, you authenticate once and get access to everything from GPT-4 to Claude to Gemini through the same endpoint.
Most builders use it to test different models quickly, set up automatic fallbacks when one provider goes down, and compare pricing across providers in real-time. It works with existing OpenAI code by just changing the base URL.
Free tier available. Paid usage is pay-as-you-go at the same rates as going direct to providers, plus a small markup.
