I wanted to try Googles Image generation models, to compliment my Claude API sub.

Holy Crap, I got about 45 minutes into setting up billing and just gave up and un-did everything.

Hint: If you want to put a spending Limit on your google cloud account, its not trivial.

I will say that Stability AI is similar to Claude, they will just let you buy credits and hit an API.

Had the same problem, wanted to use gemini but wanted to setup a speeding limit, turns out Google would prefer you to risk bankruptcy for a mistake, no spending limit available from what I understood, ended up going with openrouter and using gemini through them instead
