OpenRouter
One API for every LLM — route between Claude, GPT, Gemini, and open-source models with automatic fallbacks.
OpenRouter is a unified API gateway that gives you access to hundreds of large language models — including Claude, GPT, Gemini, Llama, Mistral, and DeepSeek — through a single endpoint. Route requests by price, latency, or intelligence, with automatic fallbacks if a provider goes down, transparent per-token pricing, and a playground to compare models. It is built for developers who want model flexibility without rewriting integration code every time a new model drops.
