I would do something like this for your use-case:

@API.route('/users', defaults={'email': None} ,methods=['GET', 'POST'])
@API.route('/users/', methods=['GET', 'POST'])
def new_user(email):
    if(email):
        user = User.query.filter_by(email=email).first()
        if user:
            return jsonify(user=user.to_json()), 200
        else:
            return jsonify(error=404), 404
    else:
        user_json = json.loads(request.get_json())
        first_name = user_json.get('first_name')
        last_name = user_json.get('last_name')
        email = user_json.get('email')
        password = user_json.get('password')
        user = User(first_name=first_name, last_name=last_name, email=email, password=password)
        db.session.add(user)
        db.session.commit()
        return jsonify(user=user.to_json()), 200
