One API shape for Gemini, Claude, Qwen, and the rest

What it does

MIXAPI is a Go-based API gateway that sits between your application and a growing zoo of large-language-model providers. It translates requests and responses so that upstream services—whether Google Gemini, Anthropic Claude, Alibaba Qwen, Moonshot Kimi, or ByteDance Doubao—can all be addressed through standard OpenAI, Claude, or Gemini protocol shapes. Behind the proxy, it handles the unglamorous but necessary work of token rotation, rate limiting, usage dashboards, and per-token billing packages.

The interesting bit

The project is an explicit descendant of New-API and One-API, folding their features plus a bundle of third-party plugins into one deployable unit. The authors claim they turned the tables by having an AI optimize the hot-path forwarding code, allegedly lifting high-concurrency throughput by more than half. Whether or not you buy the 50% figure, the real utility is the management layer: channel grouping, weighted retries, cache-aware billing, and even a built-in chat UI at /chat2link.

Key highlights

• Normalizes domestic and international models behind familiar OpenAI /v1/chat/completions, Anthropic /v1/messages, and Gemini /v1beta endpoints
• Ships as a single binary or Docker container with SQLite by default; MySQL and PostgreSQL are optional
• Granular access control: token-scoped model allowlists, channel groups, daily and per-minute rate limits, and usage logging
• Commercial-adjacent features like prepaid packages, online recharge, and balance queries without login—though the default config disables pricing display for compliance
• Redis or in-memory caching for request deduplication and channel failover retries

Caveats

• The README notes that user input is filtered to collect only Chinese characters and strip “code characters,” which is an unusual choice for a developer-facing tool and worth scrutinizing if your prompts mix languages
• It is fundamentally a derivative integration of New-API and One-API; if you already run either, many features will feel familiar rather than novel
• A “PRO” sibling repository strips consumer billing features to focus on enterprise security auditing and privacy controls, so check whether your use case maps to the open-source or commercial fork

Verdict

Worth a look if you need a self-hosted Chinese-friendly LLM router with built-in monetization primitives and you’d rather not wire up provider SDKs yourself. Pass if you want a clean-slate architecture or heavy customization beyond the provided dashboard toggles.
