XiuRouter is a model API service for developers connecting applications and AI agents to leading models through a single endpoint. Rather than requiring a separate integration per provider, it exposes each provider's native route — OpenAI Responses and Chat Completions, Anthropic Messages, and Gemini GenerateContent — so existing client code can point at XiuRouter with minimal change.
Alongside routing it provides scoped API keys, usage and cost records per key, and guided setup for 14 applications. The vendor states that selected models and service groups currently save over 90% against published provider reference prices.
Two things worth testing before moving production traffic. A router adds a network hop, so latency and rate-limit behaviour under load differ from calling a provider directly and are worth measuring against your own workload. And provider list prices move frequently — GPT-5.6 Sol dropped to $4 and $20 per million on 21 August for a three-month promotional period, and Claude Sonnet 5 rises on 1 September — so any savings figure is a snapshot rather than a fixed rate.
Best suited to teams running against more than one provider, or anyone wanting per-key cost attribution across several applications without building the accounting layer themselves.
