Hi Product Hunt! I’m Junyuan, the maker of Mustham. The main reason I built Mustham is simple: leading AI models are useful, but their official direct API costs can become expensive very quickly for independent developers and small teams. Mustham is designed to help developers complete the same kinds of AI workloads for much less. Across many supported models and routing groups, users can pay under 50% of the official direct API price while using the same model family and familiar request formats. Lower pricing should not mean unclear billing. Before choosing a route, users can compare its input, output, and cache prices. After every request, they can inspect the exact token usage and amount charged. Mustham also provides one account for OpenAI, Claude, Gemini, Grok and other models, with group-specific API keys and support for OpenAI-compatible, Responses, Claude Messages and Gemini protocols. This is an early launch, and I’d especially value feedback on pricing transparency, route selection, reliability, and API key setup. Early users can register, open Community, and send their Mustham username to receive complimentary API credits. No upvote or review is required. Thanks for taking a look! Where would paying less than half of the direct API cost make the biggest difference in your AI workflow?
