Selfie and ID matching verification API

Hello all. Sorry in advance if post is not appropriate for subreddit.

So I'm working on a software project for Uni that consists of a digital wallet. The user has to be able to verify their identity by uploading a photo of their ID and a selfie, which has to be done. Do any of you know of any API/service I can use for this? I've stumbled upon a couple of services that are paid (and expensive lol), so If any of you have used something like this for free in the past, I could really use the help.

Thanks!
