Finding the costs of extractig a page

[JonasPapinigis]

I'm looking to use this library on a relatively large scale seeded extraction. I wanted to know there is a way to expose the amount of tokens used in a single-(or even multi-)page extraction/crawl? I know I get the CrawlResult for each page, but I don't see any input/output token consumption metrics anywhere (possibly in metadata?).

My inference provider does not have a way to view EXACT costs, but I want to be able to make something like this for myself: https://github.com/orkunkinay/openai_cost_calculator

Thanks for any help!
