Blueprints for API Modules

Blueprints let you group related routes without turning the app into one giant file. That becomes especially useful once an API grows beyond a few endpoints.

from flask import Blueprint, jsonify

api = Blueprint('api', __name__, url_prefix='/api')


@api.get('/status')
def status():
    return jsonify(status='ok')

Register the blueprint on the app and keep route groups focused: auth, users, projects, or billing.
