OpenRouter
Unified API gateway giving developers access to 300+ AI models from all major providers through a single endpoint.
About
OpenRouter acts as a single access point for models from Anthropic, OpenAI, Google, Meta, Mistral, DeepSeek, xAI, and many others. You swap models by changing one parameter in your request, with no need to manage separate API keys or billing accounts per provider. The platform routes requests for higher availability and supports automatic fallbacks, while a default policy avoids logging prompts and completions. A free tier covers 26 models with daily rate limits; paid usage is billed per token at provider rates plus a small platform fee.
