erlduck is a DuckDuckGo Instant Answers API client written in Erlang/OTP.
In a nutshell, erlduck is an HTTP client application that sends HTTP requests to api.duckduckgo.com and returns the result. It uses unix1/httpclient using ninenines/gun as its HTTP backend. This means erlduck will keep configured number of workers (default 1) persistently connected to DuckDuckGo service for fast response times.

ok = erlduck:start().- and then make requests using that pool
{ok, Response} = erlduck:answer(<<"what is erlang">>).- by default the response will be JSON binary. To use XML instead
{ok, Response} = erlduck:answer(<<"what is erlang">>, xml).- to start with custom options (map may contain one more keys below):
ok = erlduck:start(#{name => other, pool_size => 2, pool_overflow => 2}).- and then use the custom pool for requests
{ok, Response} = erlduck:answer(other, <<"snakes on a plane">>).- you can still return the response in XML
{ok, Response} = erlduck:answer(other, <<"snakes on a plane">>, xml).
