I don't know why people here can't accept the simple fact that AI companies are offering cheap "unlimited" plans as a loss leader to tie you to their ecosystem, and then make up for it via add-ons, upsells, ads etc. If you use those API tokens to access external services it defeats the purpose. The hack may have worked so far, mainly because no one was checking, but they are all going to tighten the access eventually (as Anthropic and Google have already done).
Either stick to first party products or pay for API use.
