OpenRouter · screen 2About OpenRouter
OpenRouter is a unified API for large language models. It routes requests to models from OpenAI, Anthropic, Google, Meta, DeepSeek, Qwen and others through one OpenAI-compatible endpoint, with automatic fallbacks and per-model pricing on a public models page. It is for developers and startups that want to switch models without rewriting integrations. OpenRouter charges pay-as-you-go per token with no monthly fee, publishes usage rankings by model, and offers an official MCP server.

What is OpenRouter?
