What Is an API Gateway?

An API gateway sits between your client and model providers. You connect Claude Code, Codex, Cherry Studio, or your own application to Yunxi AI, and Yunxi AI forwards requests to available model services.

Request flow

Client
  -> Yunxi AI gateway
  -> authentication and model routing
  -> model provider
  -> normalized response

What it solves

• One API key can be used across multiple tools.
• Clients only need a stable Base URL.
• Balance, models, logs, and usage are visible in the console.
• Switching tools or models requires less manual configuration.

Who it is for

• Developers using AI coding tools such as Claude Code or Codex.
• Users of Cherry Studio, Open WebUI, LobeChat, or similar clients.
• Teams that want a single API key system for different model providers.
• Users who need to track balance, request logs, and model costs.
