Do I have to pay to use OpenSea?

As a cryptocurrency enthusiast and investor, I'm often on the lookout for new platforms to trade digital assets. OpenSea has been gaining popularity lately, but I'm curious about the costs involved. So, my question is: Do I have to pay to use OpenSea? Are there any transaction fees, listing fees, or other costs associated with buying, selling, or even browsing items on the platform? Clarity on this front is essential before I make any decisions regarding my digital asset portfolio.
