sixfingerdev/sixfinger-api — reverse-engineered prompt

Build me a Python service called Sixfinger that works like a fast AI chat gateway. I want one API key and one chat endpoint that lets people pick from about 16 different models, including general chat, multilingual, and coding focused options. The main chat route should accept a message, model name, and a stream flag, then return either normal JSON or streamed SSE output.

Please include plan based access control with Free, Starter, Pro, and Plus tiers, with monthly request and token quotas plus rate limits, and no daily cap logic. I also want usage tracking, a stats endpoint, and a simple health check. It should feel production ready, fast, and easy to use for support bots, coding assistants, content tools, and multilingual apps.

Make sure the API is straightforward, with clear docs and example requests like curl and Python. If it makes sense, include basic signup flow assumptions with API key management. Look up current docs online if you need to.
