I didn't find any mention to the costs spent on Claude

I've mentioned this in other replies, but I actually didn't pay for Claude directly, only via Cursor with their $20/mo subscription.

I'm using Claude for my side projects. The pricing tiers are Free (for Sonnet 3.5), $20/m for Opus 4, $100/m for max (5x usage limit as $20) and then a $200 tier above that at another 5x I believe.

The usage limits reset every 6 hours.
