Flask 1.1 is here!

From the flask release notes:

Returning a dict from a view function will produce a JSON response. This makes it even easier to get started building an API.

To get a minimal REST-Api all you have to do is:

from flask import Flask

app = Flask(__name__)

@app.route('/return_dict', methods=['GET'])
def return_dict():
    return {"x": "1"}


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