This is a Ruby library to access the DuckDuckGo Zero Click Info API.

How to install

gem install duck-duck-go


require "duck_duck_go"

ddg =
zci = ddg.zeroclickinfo("Stephen Fry") # ZeroClickInfo object

zci.heading # Stephen Fry
zci.abstract_text # Stephen John Fry is an English actor, screenwriter, author, playwright, ...
zci.related_topics["_"][0].text # Stephen Fry (cricketer) ...


This library accesses the DuckDuckGo Zero Click Info API, and returns an DuckDuckGo::ZeroClickInfo object containing the result.

Depending on the result type, the related_topics hash will contain slightly different results.

For most queries, related_topics["_"] contains an array of the related topics.

For a disambiguation query, related_topics["_"] contains the related topics, where as related_topics["Topic"] contains the disambiguation results. For example, searching for apple, you will find a related_topics["Compaines"] entry containing Apple Inc and Apple Corp, amongst others.


Source code


API and design heavily influenced by WWW::DuckDuckGo, the equivalent Perl module.
