Frequently Asked Questions
Everything you need to know about using Router One. Can't find what you're looking for? Feel free to contact us.
What is Router One?
Router One is an AI Agent infrastructure platform. It provides a unified OpenAI-compatible API endpoint that connects to 20+ LLM providers (OpenAI, Anthropic, Google, Mistral, etc.), with intelligent routing, cost optimization, and full observability — so you can run AI Agents in production safely and cost-effectively.
How do I get an API Key?
Sign up for a Router One account, then go to Dashboard → API Keys to create a new key. Your key will start with "sk-". Use it in the Authorization header as "Bearer sk-xxx".
Which models are supported?
We support models from OpenAI (GPT-4o, o1, o3, etc.), Anthropic (Claude Opus, Sonnet, Haiku), Google (Gemini), Mistral, DeepSeek, and more. Visit the Model Marketplace to browse all available models with their pricing and capabilities.
How does smart routing work?
When you set the model to "auto" or configure routing rules, Router One evaluates available providers in real time based on latency, cost, and quality weights you define per project. If one provider goes down, traffic automatically fails over to a healthy alternative — zero downtime, zero code changes.
How is billing handled?
Router One uses pay-per-token billing with no subscriptions or minimum commitments. Top up your balance via WeChat Pay, Alipay, Stripe, or cryptocurrency. If your balance reaches zero, API calls will return a 402 error — top up to resume immediately.
Is my data safe? Do you store request content?
We process requests in real time and do not retain your prompts or completions. Each request is proxied directly to the upstream provider. We only log metadata (model, tokens, cost, latency) for billing and observability — never the actual content.
How do I configure Claude Code or Codex to use Router One?
For Claude Code, set the API base URL to https://api.router.one and provide your Router One API key. For OpenAI Codex, point the OPENAI_BASE_URL environment variable to the same gateway. Detailed setup guides are available in our documentation.
What should I do if I encounter an issue?
Check the Dashboard → Logs page to inspect recent requests and error codes. Common issues: 401 (invalid API key), 402 (insufficient balance), 429 (rate limit exceeded). For further help, email contact@routerone.ai or open an issue on our GitHub.
