API Overview

WRouter speaks the industry's mainstream LLM protocols in parallel — pick whichever you want.

Base URL

https://wrouter.ai

All endpoints are HTTPS only.

Protocol compatibility

Protocol	Base path	Notes
OpenAI-style	/v1/*	The industry's most common protocol format — official and community SDKs work as drop-in
Anthropic-style	/v1/messages	Messages protocol format, for SDKs and clients that speak it
Gemini-style	/v1beta/models/{model}:generateContent	Generative AI protocol format

Point your SDK's base_url at WRouter, leave the model ID and request body as-is, and WRouter routes to the right upstream.
