Claude Proxy's Transformation Mechanisms and Implementations
Claude Proxy through innovative architectural design to achieve Anthropic's Claude API to OpenAI API format seamless conversion . The core value of this open source project lies in the lightweight proxy service implemented through Bash scripts, which can instantly convert Claude API request parameters and response formats to the standard specification of OpenAI API. Developers can call the Claude series of models like the OpenAI API, significantly reducing integration costs.
The conversion features of the tool are mainly manifested in three key aspects: first, the automatic adaptation of the request body format, which converts the OpenAI standard messages array into the prompt format accepted by Claude; second, the standardization processing of the response structure, which re-encapsulates Claude's original response into the OpenAI standard JSON structure; and finally, the streaming response compatibility processing to ensure that the Server-Sent Events (SSE) function flows perfectly between the two APIs.
The project is modularized and developers can modify theclaude_proxy.shConfiguration of variables in the script to flexibly match different versions of the API specification. For example, mapping model names togemini-1.5-promaybegpt-4o-miniand other arbitrary identifiers to meet the identification requirements of various front-end tools.
