How do I build an API using Flask?

To build an API with Flask, you need to install Flask, set up a basic app, and define your routes.

What are the essential libraries I need to install?

You should install Flask and Flask-RESTful for building REST APIs. You can do this using pip.

Can you show me a simple example of a GET endpoint?

Sure! Here's a simple example:

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/api/data', methods=['GET'])
def get_data():
    return jsonify({'message': 'Hello, World!'})

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

How do I test my API?

You can test your API using tools like Postman or curl. Just send a GET request to your endpoint.
