Overview - PIPELLM Docs

PipeLLM exposes native public routes and converter routes. Use this section when you need the exact path, headers, request format, error behavior, and rate limit rules for PipeLLM’s public API.

Public Endpoint Families

Request format	Native route	Converter route	Use this when
OpenAI Chat Completions	`/v1/chat/completions`	`/openai/v1/chat/completions`	Use the native route for OpenAI-compatible platforms. Use the converter route to keep OpenAI format while calling Anthropic or Gemini models.
OpenAI Responses	`/v1/responses`	Not available yet	Use the native route for OpenAI-compatible platforms. For cross-protocol calls today, use the OpenAI Chat Completions converter instead.
Anthropic Messages	`/v1/messages`	`/anthropic/v1/messages`	Use the native route for Anthropic-compatible platforms. Use the converter route to keep Anthropic format while calling OpenAI or Gemini models.
Gemini Generate Content	`/v1beta/models/{model}:generateContent`	`/gemini/v1beta/models/{model}:generateContent`	Use the native route for Gemini platforms. Use the converter route to keep Gemini format while calling OpenAI or Anthropic models.
