Router One

Router One is a unified LLM API gateway that provides a single OpenAI-compatible endpoint (https://api.router.one/v1) for accessing models from OpenAI, Anthropic, Google, Grok, and more. It enables smart routing, same-model fallback, and per-request cost observability without requiring changes to existing SDKs or code.

Key Features:

• Unified API: One base URL and API key for all supported models; compatible with OpenAI SDK, Anthropic SDK, Codex CLI, and Claude Code.
• Smart Routing & Fallback: Automatically selects eligible provider routes for the requested model and falls back to another provider serving the same model on retryable errors, ensuring continuity.
• Cost Observability: Detailed traces per request showing final model, provider, token usage, cost, latency, and status; per-API-key cost tracking and spend caps.
• Flexible Billing: Pay-as-you-go wallet top-ups via credit card, Alipay, or stablecoins (USDT/USDC); optional monthly subscription tiers with shared request quotas.
• China Access: Direct connectivity from mainland China without VPN, with published latency benchmarks.
• Data Privacy: Prompts and responses are forwarded in real-time and not persisted; only metadata retained per data retention policy.

Target Audience: AI application developers, teams building AI agents, companies using coding assistants (Claude Code, Codex CLI), and organizations needing reliable multi-model LLM access with cost control.

Value Proposition: Reduce vendor lock-in, improve resilience via automatic fallback, gain full visibility into LLM spend, and simplify integration with existing tools.
