DuckDuckGo’s language “Browsers preferred language” (<code class="docutils literal notranslate"><span class="pre">wt_WT</span></code>) makes no

is <code class="docutils literal notranslate"><span class="pre">wt-wt</span></code> (the region).</p>
<p>Beside regions DuckDuckGo also defines its languages by region codes. By
example these are the english languages in DuckDuckGo:</p>
<ul class="simple">

</dl>
<p>TL;DR; the <code class="docutils literal notranslate"><span class="pre">vqd</span></code> value is needed to pass DDG’s bot protection and is used
by all request to DDG:</p>
<ul class="simple">
<li><p>DuckDuckGo Lite: <code class="docutils literal notranslate"><span class="pre">https://lite.duckduckgo.com/lite</span></code> (POST form data)</p></li>
<li><p>DuckDuckGo Web: <code class="docutils literal notranslate"><span class="pre">https://links.duckduckgo.com/d.js?q=...&vqd=...</span></code></p></li>
<li><p>DuckDuckGo Images: <code class="docutils literal notranslate"><span class="pre">https://duckduckgo.com/i.js??q=...&vqd=...</span></code></p></li>
<li><p>DuckDuckGo Videos: <code class="docutils literal notranslate"><span class="pre">https://duckduckgo.com/v.js??q=...&vqd=...</span></code></p></li>
<li><p>DuckDuckGo News: <code class="docutils literal notranslate"><span class="pre">https://duckduckgo.com/news.js??q=...&vqd=...</span></code></p></li>
</ul>
<p>DDG’s bot detection is sensitive to the <code class="docutils literal notranslate"><span class="pre">vqd</span></code> value. For some search terms
(such as extremely long search terms that are often sent by bots), no <code class="docutils literal notranslate"><span class="pre">vqd</span></code>
value can be determined.</p>
<p>If SearXNG cannot determine a <code class="docutils literal notranslate"><span class="pre">vqd</span></code> value, then no request should go out
to DDG.</p>
<div class="admonition attention">
<p class="admonition-title">Attention</p>
<p>A request with a wrong <code class="docutils literal notranslate"><span class="pre">vqd</span></code> value leads to DDG temporarily putting
SearXNG’s IP on a block list.</p>
</div>
<p>Requests from IPs in this block list run into timeouts. Not sure, but it
seems the block list is a sliding window: to get my IP rid from the bot list
I had to cool down my IP for 1h (send no requests from that IP to DDG).</p>

<p>The <a class="reference external" href="https://duckduckgo.com/api">DDG-API</a> is no longer documented but from
reverse engineering we can see that some services (e.g. instant answers) still
in use from the DDG search engine.</p>
<p>As far we can say the <em>instant answers</em> API does not support languages, or at
least we could not find out how language support should work. It seems that
most of the features are based on English terms.</p>
