Customizing User-Agent string when using curl or Python requests

The Linux tool cURL and the Python requests library can both be used to submit GET requests to REST API endpoints. On some sites, however, you will get 403 Forbidden or 401 Unauthorized errors unless you change your User-Agent string to something other than "curl" and "python requests". As of July 2017, I have had good results by changing my User-Agent string to "Mozilla/5.0".

For curl, the option to change the user agent string is -A or --user-agent

For Python requests, you can add the user-agent string to the headers argument in your get request:

response = requests.get("https://api.coinone.co.kr/orderbook?currency=eth", headers={'User-Agent': 'Mozilla/5.0})
