# bnrouter > bnrouter is an AI API gateway that routes, meters, and monetizes access to > multiple large-model providers behind a single OpenAI-compatible endpoint. ## Key facts - **What it is:** A production-grade AI API gateway — one key, one endpoint, unified quotas, and one usage dashboard across many model providers. - **Protocol:** OpenAI-compatible chat & embeddings API. Swap models without rewriting client code. Any OpenAI-compatible client (OpenAI SDK, LangChain, and similar) works by pointing its base URL at the gateway. - **Supported model families:** Claude, GPT, Gemini, Kimi, DeepSeek, Qwen, Grok, Llama, Flux, DALL·E, Stable Diffusion, and other major chat, embedding, image, and video models, depending on the live upstream channels configured in the model plaza. - **Billing:** No setup fee and no monthly commitment. Pay-as-you-go balance top-ups, quota-based subscription plans, and redeem codes — metered per million tokens. - **Security:** Requests are forwarded to model providers over encrypted channels; prompts and completions are not stored, only usage metadata. - **Languages:** The site and console are available in English, Simplified Chinese (简体中文), 日本語, 한국어, Русский, and Bahasa Melayu. - **Deployment:** Static marketing site, merchant console, and admin console served across three subdomains. ## Pages - [Home (English)](/en/) - [Home (简体中文)](/zh/) - [Home (日本語)](/ja/) - [Home (한국어)](/ko/) - [Home (Русский)](/ru/) - [Home (Bahasa Melayu)](/ms/) - [Quickstart (English)](/en/quickstart/) - [Quickstart (简体中文)](/zh/quickstart/) - [Quickstart (日本語)](/ja/quickstart/) - [Quickstart (한국어)](/ko/quickstart/) - [Quickstart (Русский)](/ru/quickstart/) - [Quickstart (Bahasa Melayu)](/ms/quickstart/) - [Docs (English)](/en/docs/) - [Docs (简体中文)](/zh/docs/) - [Docs (日本語)](/ja/docs/) - [Docs (한국어)](/ko/docs/) - [Docs (Русский)](/ru/docs/) - [Docs (Bahasa Melayu)](/ms/docs/) - [Tooling Docs (English)](/en/docs/tooling/) - [Tooling Docs (简体中文)](/zh/docs/tooling/) - [Tooling Docs (日本語)](/ja/docs/tooling/) - [Tooling Docs (한국어)](/ko/docs/tooling/) - [Tooling Docs (Русский)](/ru/docs/tooling/) - [Tooling Docs (Bahasa Melayu)](/ms/docs/tooling/) - [Agents (English)](/en/agents/) - [Agents (简体中文)](/zh/agents/) - [Agents (日本語)](/ja/agents/) - [Agents (한국어)](/ko/agents/) - [Agents (Русский)](/ru/agents/) - [Agents (Bahasa Melayu)](/ms/agents/) - [Pricing (English)](/en/pricing/) - [Pricing (简体中文)](/zh/pricing/) - [Pricing (日本語)](/ja/pricing/) - [Pricing (한국어)](/ko/pricing/) - [Pricing (Русский)](/ru/pricing/) - [Pricing (Bahasa Melayu)](/ms/pricing/) - [FAQ (English)](/en/faq/) - [FAQ (简体中文)](/zh/faq/) - [FAQ (日本語)](/ja/faq/) - [FAQ (한국어)](/ko/faq/) - [FAQ (Русский)](/ru/faq/) - [FAQ (Bahasa Melayu)](/ms/faq/) - [Sign in](/app/sign-in) - [Sign up](/app/sign-up) ## FAQ **What is bnrouter?** bnrouter is an AI API gateway. It aggregates multiple large-model providers behind a single OpenAI-compatible endpoint, so your application talks to one API instead of many. **How is it different from calling providers directly?** Instead of managing separate accounts, SDKs, and billing for every provider, you get one key, one endpoint, unified quotas, and one usage dashboard — while models remain interchangeable. **Is it free to use?** The gateway itself has no setup fee and no monthly commitment. You only pay for the model usage you consume, either via balance top-ups, quota-based subscription plans, or redeem codes. **Is my data safe?** Yes. Requests are forwarded to the model providers over encrypted channels. We do not store your prompts or completions; only usage metadata is kept for billing and analytics. **Which models are available?** The catalog covers major chat, embedding, image, and video model families including Claude, GPT, Gemini, Kimi, DeepSeek, Qwen, Grok, Llama, Flux, DALL·E, Stable Diffusion, and more. Availability can vary by upstream channel, so check the model plaza in the console for the live list. **Does it work with OpenAI-compatible clients?** Yes. The endpoint implements the OpenAI chat and embeddings protocol, so the OpenAI SDK, LangChain, and other OpenAI-compatible clients work by simply pointing the base URL at bnrouter and using your key. **Can I start without a long-term commitment?** Yes. There is no setup fee and no minimum spend. Create an account, top up a small balance, and pay only for the usage you consume. **Do you support multiple languages?** Yes. The console and this site are available in English, Simplified Chinese, Japanese, Korean, Russian, and Bahasa Melayu.
