URL Parameters

You can change DuckDuckGo settings via URL parameters by adding them after the search query, for example: https://duckduckgo.com/?q=search&kp=-1&kl=us-en.

These parameters are intended for individual use. If using them for any other purpose beyond individual use (e.g. for apps/extensions), please do not remove our branding (ko, kr params etc.) or advertising (k1, k4 params etc.) as we have contracts in place that we would be violating if you did so. Please see our partnerships page for more info on guidelines and getting in touch with us.
