XiuRouter

XiuRouter, operated by XiuLab Inc, gives developers one API endpoint and one key for GPT, Claude, DeepSeek and other models in its current catalog. It accepts requests in several native API formats, so existing SDKs and coding agents can usually switch by changing only the base URL and API key.

What It Is

XiuRouter is a model API gateway that sits between an application and multiple model providers. Instead of managing separate accounts and credentials for each provider, developers send requests to XiuRouter and choose a model by name. The service reports usage and cost per request and provides a web playground for testing requests before wiring them into an app.

Supported Request Formats

XiuRouter accepts four request formats: OpenAI Chat Completions, OpenAI Responses, Anthropic Messages, and Gemini GenerateContent. The documentation notes that format support is not the same as model availability: the Gemini format is supported for Gemini-native clients, but the current public catalog does not list Gemini or Grok models. The docs also caution that converting between formats can affect tool calls, structured output and token counting, that the Responses route is stateless, and that a model working through one format should be tested in the others before production use.

Models and Service Tiers

The catalog is split into two service tiers. The Value tier offers lower prices with variable availability, while the Managed tier is operated through XiuStore for more consistent results. The current catalog includes Claude and GPT model families plus DeepSeek, and the pricing page lists each model's rates next to the provider's reference price.

Coding Tool and App Integrations

App-specific setup guides cover coding agents and chat apps including Codex, Claude Code, Cursor, Cline, Continue, Aider, OpenCode, Open WebUI and LibreChat. Signed-in users can generate account-specific configuration and verify a real request from the guide.

Usage Visibility

A usage dashboard tracks cost, tokens and latency per request, and a public rankings page shows which models are used most. According to XiuLab, XiuRouter does not retain prompt or conversation content.
