About OpenRouter
OpenRouter gives one API key access to more than 500 models from over 80 providers, covering text, images, video and audio. When a provider goes down, requests can fall back to another one, and data policies let you restrict prompts to providers you trust.
It charges for usage without subscriptions and publishes model prices and usage rankings. A web chat is available for trying models directly, and many applications and coding agents use OpenRouter as their model backend.
