# Crazyrouter Docs

> Find Crazyrouter API guides, tool integrations, model capabilities, and AI-readable documentation by task

> Last updated: 2026-06-16

<Note>
  API routes: the default international entry is `https://api.crazyrouter.com`; for East Asia, prefer `https://cn.crazyrouter.com`. OpenAI-compatible clients usually add `/v1`; Claude Code and Anthropic-native clients use the root domain without `/v1`. See [API Endpoints](/en/api-endpoint).
</Note>

Crazyrouter is a unified AI model API gateway. Use one API key for text, image, video, audio, embeddings, rerank, and the model access needed by common AI tools.
