What is a user-agent string

Browsers and web crawlers send a special identification, called the user-agent string, to the website they're accessing. This user-agent can be used to tailor the reply, for example: when the user-agent string makes it clear that the website is being accessed on a phone the mobile variant of the website may be returned. If the web server software keeps a logs of all visitors to the website it usually also stores the user-agent string to allow identification of the different traffic.

Default user-agent string

By default, ContentKing sends this user-agent string when making requests:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36 (+https://whatis.contentkingapp.com)

This may change in the future, so check this page regularly for updates.
