I am new in creating API. But I created one like this code :

app = Flask(__name__)
@app.route("/",methods=['GET','POST'])
def hello():
    try :
        with open('logs.txt','a') as f :
            f.write(f"{datetime.now()}\n")
    except Exception as e :
        print(str(e))
    value = request.args.get('symbol')
    result = database.get_symbol(value)
    return jsonify(result)
if __name__ == '__main__':
    app.run(debug=False)

So I have a VPS (Virtual private server) with windows7 on it and I am trying to run my flask app in it. but when I run it the code will be like this :

main.py:443: DeprecationWarning: use options instead of chrome_options
  return webdriver.Chrome(chrome_options=option)
 * Serving Flask app "main" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

But when I run it in my server and trying to access it using my own personal computer with this code :

curl [ip_address]:5000/?symbol=value

it give me an error : 

curl: (7) Failed to connect to [IP] port 5000: Connection refused

How can people use this API?

can I just deploy it in developer mode?

127.0.0.1 is your own IP address that can be accessed only from that PC.

if __name__ == '__main__':
    app.run(debug=False, host=<VPS's IP address>)

Instead of assigning, you can write 0.0.0.0, and specify the VPS's IP address when connecting from outside.
