How to use url_map.iter_rules with blueprint object instead of app

Question

I have a blueprint object "api" and a apis.py file where I have many APIs defined with api.route annotation. eg:

@api.route('/', methods=['GET'])
def get_info():

I want to iterate and get summary of all the APIs I have same as what we get when we use "url_map.iter_rules" on app object. How can we do this using api blueprint object? I have registered the blueprint in my init.py file using

from .api_1 import api as api_blueprint
app.register_blueprint(api_blueprint)

I think if you call app.url_map.iter_rules() after you've registered the blueprint you'll get all of the endpoints of the subdomains too, e.g.

api.py

from flask import Blueprint
api = Blueprint('api', __name__)
@api.route('/')
def call_api():
        return ""

init.py:

from flask import Flask, Blueprint
from api import api

public = Blueprint('public', __name__)
@public.route('/')
def home():
        return render_template('public/home.html')


app = Flask(__name__)
app.register_blueprint(public)
app.register_blueprint(api, subdomain='api')
print(list(app.url_map.iter_rules()))

[<Rule 'api|/' (GET, HEAD, OPTIONS) -> api.call_api>,
 <Rule '/' (GET, HEAD, OPTIONS) -> public.home>,
 <Rule '/static/<filename>' (GET, HEAD, OPTIONS) -> static>]
