WindsurfAPI acts as a crucial intermediary, translating standard OpenAI and Anthropic API requests into Windsurf's proprietary gRPC protocol to access a wide array of over 100 language models, including Claude, GPT, Gemini, Grok, and more. This Node.js-based HTTP service exposes both OpenAI-compatible (`/v1/chat/completions`) and Anthropic-compatible (`/v1/messages`) endpoints, allowing developers to use existing SDKs directly. Beyond simple translation, WindsurfAPI incorporates advanced operational features. It manages an account pool, automatically rotating accounts to ensure continuous access, implements rate limiting to prevent abuse or service interruptions, and provides fault tolerance through automatic failover mechanisms. The proxy also strips identity information from upstream Windsurf responses, making models appear as if they are directly from the original providers (e.g., "I am Claude Opus 4.6 developed by Anthropic"). For specific use cases like Claude Code, Cline, or Cursor, it supports tool_use and tool_result paradigms, where the API merely passes these instructions, and the client-side CLI executes file operations locally. The project emphasizes ease of deployment with one-click setup scripts and Docker support, including persistent data volumes for configurations and logs, and simplified updates.
