Unlike the standard embedding method that use script like this
<pre><code><script src="https://gist.github.com/..."></script>
</code></pre>
to embed gist code, Gist API Code insert plugin inserts code directly in to your posts using simple shortcode and highlights it with prism code highlighter.
Examples
Add all files from a gist:
<pre><code>[apCI id="123456789"]
</code></pre>
Add single file from a gist:
<pre><code>[apCI id="123456789" file="filename.php"]
</code></pre>
Add single file from a gist with raw file link:
<pre><code>[apCI id="123456789" file="filename.php" raw="yes" ]
</code></pre>

Gist API Code insert

Inserts Github Gist code directly in to your posts via shortcode without using js embed script
