[Python] Add prefix to all URLs while using Blueprint

I am trying to prefix all endpoints with /api/, but I am getting 404 in return if not providing directly in the URL or while registering blueprint.

main.py

from init import app

from modules.User import User

app.register_blueprint(User)

if __name__ == "__main__":
app.run(debug=True)


init.py

from flask import Flask

# initiating application instance
app = Flask(__name__)

# app configurations
app.config["SCRIPT_NAME"] = "/api/"

# -- OR --

app.config["APPLICATION_ROOT"] = "/api/"
...


modules/User.py

from flask import request, Blueprint

User = Blueprint("user_blueprint", __name__)

# if "/api/" is provided directly
@User.route("/api/", methods=["GET"])
def get():
return "Called get method"


# 404 if "/" is provided
@User.route("/", methods=["GET"])
def get():
return "Called get method"
