The majority of edX courses are entirely free to access and most offer an optional paid verified certificate track with graded assignments and the opportunity to work towards a certificate for a fee that varies per course. The Verified track awards a certificate after you successfully pass the course. Verified certificates are a great way to showcase the skills and knowledge you've gained, and can help advance your professional or academic career.
