LLM API that's paid by users, not dev

Yo,

I've been building funny side projects involving AI. E.g. halupedia com which got 300k users in few week and major media coverage.

I paid like $250-350 in API costs. Wanted even to add image feature but would go bankrupt.

I know a lot of people want to build something funny or for portfolio without worrying about costs. Imagine you have an AI presentation software in mind but having to create entire paywall just not to lose money's too much for sth you'd like to build, publish and forget.

At least that were my problems, so I created Wattfare - OAuth for AI spent. User clicks a button, accepts and you have access to their AI budget.

Would appreciate some thoughts from you
