How much would it cost to use google oauth to just get name, email and user ID of user?

[kartiktambi]

Hi all, I am new here... I am planning to use google oauth (externally without firebase or others) in my webapp using a "sign in with google" button, to just get me the user's email, name, and the unique google user id, which I would store and use later in my app.

I have never used google cloud platform or built with google oauth before, so I wanted to know what could be the pricing of using oauth consent screen and getting email/name/userID from google of the user (i do not need any access to anything of the user, just want basic profile info)? i looked around on cloud platform pricing page but ended up even more confused than i was... Essentially I want to know what would it cost me to use a simple "sign in with google" button to get user's basic details name/email/user id from google. Any help is appreciated, Thanks!
