# Welcome to ClearMaas

> One API. Multi-provider. Zero markup.

ClearMaas is an OpenAI-compatible API gateway. Point your existing
OpenAI SDK at `https://api.clearmaas.com/v1` and route requests across
OpenAI, Anthropic, Google Gemini, DeepSeek, xAI Grok, Alibaba Qwen,
Moonshot Kimi, MiniMax, and Kling (video) — at provider cost price.

## Why ClearMaas

<CardGroup cols={2}>
  <Card title="Zero markup, ever" icon="circle-dollar-to-slot">
    You pay the provider's published price per token. ClearMaas's revenue
    comes from optional paid subscription plans, not from inflating your
    token cost.
  </Card>

  <Card title="OpenAI-compatible by design" icon="code">
    Every request and response is in the OpenAI JSON shape. Change one
    line (`base_url`) and your existing code keeps working — streaming,
    tool calling, vision, and reasoning all behave the way your SDK
    expects, with the gateway translating to each upstream as needed.
  </Card>

  <Card title="Speaks every protocol natively" icon="languages">
    ClearMaas exposes OpenAI, Anthropic, and Gemini surfaces directly,
    and translates between them when you call across protocols (e.g.
    OpenAI SDK → Claude). New provider features that aren't in the
    common shape stay reachable on the native path.
  </Card>

  <Card title="Smart routing" icon="route" href="/routing/model-fallbacks">
    Fallback chains via `extra_body.models`, named routers, and
    `clearmaas/auto` for cheapest-live-model selection.
