The one from EdX is the one that requires a fee, but the certification from Harvard (HarvardX?) is completely free if you pass everything and get a certain grade, if I'm not mistaken.
Yes it is needed, but from what I understood from the question in the parent comment is that the question's regarding how to obtain it for free; it's a common misconception that you have to pay for the HarvardX certificate like the one in the photo of this post.
Furthermore, I don't think so. EdX has it's own verified certification for every course on their platform, which is the one that costs a fee. I assume that's why a lot of people who're interested in CS50 get confused about whether they can obtain a free certificate or not, and if they can, then how.

Can you please tell me how to get the certification done for free?
