What is OpenRouter?
OpenRouter is a single interface that connects you to hundreds of AI models from many providers. Instead of signing up for each provider separately, you get one API key that works with models like Gemini, GPT, and Claude. It handles text, images, videos, and audio through the same unified endpoint.
You start by creating an account, then buy credits that work with any model or provider. After that, you generate an API key and start making requests. The API is fully OpenAI compatible, so if you already use OpenAI, you can switch to OpenRouter with minimal changes to your code.
OpenRouter runs on distributed infrastructure across 80+ providers. If one provider goes down, your requests automatically fall back to another. You can also set custom data policies to control which models and providers your prompts go to. The site mentions 500+ models, 500T+ monthly tokens, and 10M+ global users.

What to check before you rely on OpenRouter
- Verify your credit balance and per-model pricing before production use, since OpenRouter's site lists freemium but does not state exact credit costs or minimum purchase amounts.
- Check which providers and models honor your custom data policies, as OpenRouter does not specify how each provider handles data retention or compliance.
- Confirm your target models are available and their fallback behavior, since OpenRouter does not list which providers support automatic failover for every model.
