Crazyrouter

Crazyrouter is an AI API gateway for developers working with models from multiple providers. It brings access to models from OpenAI, Anthropic, Google, and other providers into one service, using one API key and an OpenAI-compatible API. It also supports coding tools such as Claude Code and Codex CLI. Developers can use Crazyrouter when building applications that need access to different AI models, testing model choices, or setting up a coding workflow. A common integration reduces the need to maintain a separate client setup for every supported provider. The website provides documentation and a model catalog to help users configure requests and check available options. Crazyrouter is a paid service with prepaid, usage-based billing. Charges depend on the selected model and usage. Developers should consult the current model catalog and pricing before choosing a model or integrating the service into their application. There is no free usage allowance. The service is designed for users comfortable with API keys, model selection, and application configuration.
