MaxRouter is an enterprise-grade AI API gateway that provides unified access to 18+ frontier models — including GPT-5.5, Claude Opus 4.8, Gemini 3.5 Flash, and Grok 4.3 — through a single OpenAI-compatible API endpoint. No need to manage multiple API keys or vendor integrations.
Is it compatible with the OpenAI SDK?
Yes. Our API is fully compatible with the OpenAI API format. You can use existing OpenAI SDKs (Python, Node.js, etc.) with zero code changes — just swap the base URL to https://api.silom.cn/llm-api/v1 and use your MaxRouter key.
Which coding tools are supported?
Any tool that supports custom API endpoints works with MaxRouter. This includes Claude Code, Cursor, Cline, Codex CLI, Cherry Studio, Trae, Windsurf, and more. We provide step-by-step setup guides for each tool.
What output formats are supported?
We support OpenAI Chat Completions, Anthropic Messages, streaming (SSE), tool calling / function calling, structured output (JSON mode), and image generation. All standard OpenAI API features work out of the box.
How does pricing work?
We use transparent per-token pricing. You only pay for what you use — no subscriptions, no minimum spend, no hidden fees. Top up anytime, and your balance never expires. See our Models & Pricing page for detailed rates.
Is there a minimum top-up amount?
No. There is no minimum top-up amount. You can add any amount to your balance at any time. Your balance never expires.
Are there enterprise volume discounts?
Yes. For enterprise customers with significant monthly usage, we offer custom pricing and dedicated support. Contact us to discuss volume discounts tailored to your needs.
Do you store my API request data?
No. We do not store, log, or train on your API request or response data. Your prompts and completions are forwarded directly to the upstream model provider and are not retained on our servers. See our Privacy Policy for details.
Is the API connection encrypted?
Yes. All API connections use TLS 1.3 encryption. Your API keys and data are encrypted in transit at all times.
