Crazyrouter is an AI API gateway that lets developers call hundreds of AI models, including Claude, GPT and Gemini, through one API key with OpenAI-compatible endpoints.
About
Crazyrouter is an AI API gateway that gives developers a single account and API key for reaching a large catalog of AI models from multiple providers. Instead of registering separately with each provider and managing different credentials, developers route their requests through Crazyrouter, which exposes OpenAI-compatible APIs as well as model-specific native interfaces. This solves a common integration problem: applications and AI coding tools can switch or compare models without rewriting their connection code.
The service advertises access to more than 300 models, including Anthropic's Claude, OpenAI's GPT, and Google's Gemini families. It provides native integration guides for coding assistants such as Claude Code, Codex CLI, and Cursor, and supports pay-as-you-go billing. The base URL for OpenAI-compatible SDKs is https://api.crazyrouter.com/v1. Pricing pages are available in English, Chinese, Japanese, Korean, and Russian, and the product site and documentation are published in English and Chinese.

Who It's For
Crazyrouter is aimed at developers and engineering teams who build applications or workflows on top of large language models. Typical users include backend developers consolidating multi-provider API access under one key, teams using coding assistants like Claude Code, Codex CLI, or Cursor who want a single gateway for those tools, and independent builders who want to compare model prices before committing. It is also practical for developers in regions served by its payment and invoicing options, since the service is documented bilingually and supports metered billing.
