What are you guys finding the best way to track cost per call? I'm trying to get a sense of how much it costs us per page (we process pdf's). I've got something close to working but I seem to be consistently off what google is billing me for gemini. I'm not off by a fixed percent either.

If you figure it out, let me know! I switched over to llamaindex parse, which is kind of expensive, but very good, and easy to track costs. But I'm still experimenting with other options.
