Developer ToolLLM API Gateway
A unified, OpenAI-compatible API gateway providing smart model routing, automatic fallback, and cost tracking for multiple LLM providers.
What it does
Router One serves as a centralized abstraction layer for interacting with various large language models, including GPT, Claude, Gemini, and DeepSeek. By offering a single, OpenAI-compatible interface, it allows developers to integrate multiple LLMs into their applications without managing separate API keys or complex code changes for each provider. The platform features intelligent routing to optimize model selection, automatic fallback mechanisms to ensure service continuity during provider outages, and granular per-request cost tracing for precise budget management. It also aims to reduce friction for global developers by removing the necessity for US-based payment methods.
Core features
- •Unified OpenAI-compatible API interface
