## What is RuAPI

**RuAPI** gives you access to the world's leading AI models through one key.
One API key, one OpenAI-compatible SDK, one USDT balance — and you work with dozens of models from different providers without opening an account at each of them.

**At a glance:**

* **Protocols:** OpenAI-compatible (`base_url https://www.ruapi.ai/v1`) and native Anthropic (`https://www.ruapi.ai`, **without** `/v1`).
* **Payment:** USDT or USDC — TRC20 / BEP20 / Polygon networks, \$5 minimum. No bank card needed — though you can also pay by Visa / Mastercard.
* **Providers:** OpenAI, Anthropic Claude, Google Gemini, xAI Grok, DeepSeek, Zhipu GLM, MiniMax, Alibaba Qwen, Xiaomi MiMo and others — one key for all.
* **Who it's for:** developers and teams in Russia and the CIS; access without a VPN.

## Who is it for

* **Developers** in regions where bank cards are blocked or unreliable for foreign AI services.
* **Teams** that need multiple models in one project — separate accounts at each vendor become a chore.
* **Researchers** who want to quickly compare Claude / GPT / Gemini answers on the same prompt.

## How it works

<Steps>
  <Step title="Sign up">
    Create an account on [www.ruapi.ai](https://www.ruapi.ai) with email and password.
  </Step>

  <Step title="Top up">
    Send USDT or USDC via TRC20, BEP20 or Polygon — your balance updates automatically once the transaction is confirmed.
  </Step>

  <Step title="API key">
    In the **Tokens** section, generate an API key (starts with `sk-...`) and copy it.
  </Step>

  <Step title="First request">
    Set `base_url=https://www.ruapi.ai/v1` in your OpenAI SDK and call any supported model.
    For Anthropic (Claude Code) the address is **without** `/v1`: see [Base URL](/en/quickstart).
  </Step>
