<span class="sd">DuckDuckGo Instant Answer API</span>
<span class="sd">~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</span>
<span class="sd">The `DDG-API &lt;https://duckduckgo.com/api&gt;`__ is no longer documented but from</span>
<span class="sd">reverse engineering we can see that some services (e.g. instant answers) still</span>
<span class="sd">in use from the DDG search engine.</span>
<span class="sd">As far we can say the *instant answers* API does not support languages, or at</span>
<span class="sd">least we could not find out how language support should work. It seems that</span>
<span class="sd">most of the features are based on English terms.</span>
