Five hundred stars for a README and a proxy

What it does 云雾API (yunwu.ai) is a commercial API relay that provides domestic access to OpenAI, Anthropic, and other Western model providers, billing in yuan at a 0.5:1 rate against official dollar pricing. This repository contains no source code; it is a Chinese-language landing page that links to account top-ups, free API key giveaways, hosted chat mirrors, and setup tutorials for popular third-party clients.

The interesting bit The project treats GitHub as a storefront. It has accumulated 506 stars with nothing but pricing tables, Python snippet links, and configuration guides for tools like Cursor, LobeChat, and chatgpt-on-wechat. The value proposition is purely logistical: domestic routing that avoids the need for a VPN, plus RMB billing.

Key highlights

• Claims support for 207+ models, including GPT-4o, Claude, and text-embedding families
• Self-reported pricing at ¥0.50 for every $1 of official token cost
• Curated integration docs for roughly a dozen third-party apps and frameworks
• Offers free API keys and hosted web mirrors via external subdomains
• Claims 99.9% uptime and unlimited concurrency in its FAQ

Caveats

• The repository contains no open-source code; it is strictly a marketing and documentation hub for a paid third-party proxy
• “Official relay” branding is operator marketing language, not an OpenAI partnership or endorsement
• All performance, pricing, and stability figures come from the service provider without independent verification

Verdict Mainland developers who need RMB billing and direct routing to LLM APIs without a VPN might bookmark the client configuration links. If you are looking for an open-source project to inspect, fork, or self-host, this is not it.
