[update]: This was the preferred method until google recently discontinued it (writing as of dec 2021).
Your first example should work without the name= part.
This did the job for me:
<pre><code>video.google.com/timedtext?lang={languageID}&amp;v={videoId}
</code></pre>
To fetch the english CC version from the previous answer, it would look like this:
<pre><code>http://video.google.com/timedtext?lang=en&amp;v=zzfCVBSsvqA
</code></pre>

If <code>video.google.com</code> does not fetch your closed caption file OR you don't want your file in XML format, but would rather SRT (see note below), try:

<a href="http://ccsubs.com" rel="nofollow noreferrer">CC SUBS</a>

NOTE: SRT can be transformed into virtually ANY format - either using free subtitling tools OR
by replacing <code>\n\n</code> with <code>|</code>, <code>\n</code> with <code>;</code> and then <code>|</code> into <code>\n</code>, you get a CSV file that can be opened in a spreadsheet, for example.

Here my suggestions after spending some time:

</ul>

Does any one know how to get the CC for any Youtube video that has the caption available? I know on the API 2.0 documentation mentions that it is only available for the owner of the video... but I was able to get some of the video's caption even though I'm not the owner of any....

There are two APIs (or links to API) can be used. they both rout to timpedtext API.
before I mention them we should note the parameters the API need. which are:

<ul>
<li><code>lang: {en, fr,...}</code> required.</li>
<li><code>v: {video ID}</code> required.</li>
<li><code>name</code>: the track name, Required only if it is set. (and with this is my problem.)</li>
<li><code>tlang</code>: translation to language. optional (should be set if you like to translate the CC to other language. </li>
</ul>

The API links are:

<ol>
<li><a href="http://video.google.com/timedtext?lang=fr&amp;v=PILzP-bIeLo&amp;name=french" rel="noreferrer">http://video.google.com/timedtext?lang=fr&amp;v=PILzP-bIeLo&amp;name=french</a>
Note the above example would return nothing if you remove the name=French or set it to something else...</li>
<li><a href="http://www.youtube.com/api/timedtext?v=zzfCVBSsvqA&amp;lang=en" rel="noreferrer">http://www.youtube.com/api/timedtext?v=zzfCVBSsvqA&amp;lang=en</a>
Note this example would return nothing if you set the name=...</li>
<li><a href="http://www.youtube.com/api/timedtext?v=ZdP0KM49IVk&amp;lang=en" rel="noreferrer">http://www.youtube.com/api/timedtext?v=ZdP0KM49IVk&amp;lang=en</a>
yet the actual video has caption.</li>
</ol>

Example 3 does not return the CC data.

So I'm guessing that example 3 need to have the name parameter set. and my main problem is how do I find the name parameter if it is set or not. and if it is set how do I know what is it?

有没有人知道如何获得任何有标题的Youtube视频的CC？我知道在API2.0文档中提到，它只对视频的所有者可用.但我得到了一些视频的说明，尽管我不是任何.可以使用两个API(或指向API的链接)。它们都会转到timpedtext。在我提到它们之前，我们应该注意API需要的参数。它们是：需要lang: {en, fr,...
