Get the number of facebook *shares* of a specific URL
This API is no longer available. The answer below is no longer valid.
I could get stats of a page (say http://techcrunch.com) with just a GET request to API. Just place this GET request http://api.facebook.com/restserver.php?method=links.getStats&urls=[YOUR_URL]
and get the stats.
like http://api.facebook.com/restserver.php?method=links.getStats&urls=http://techcrunch.com/ returns
<links_getStats_response xsi:schemaLocation="http://api.facebook.com/1.0/ http://api.facebook.com/1.0/facebook.xsd" list="true">
<link_stat>
<url>http://techcrunch.com/</url>
<normalized_url>http://www.techcrunch.com/</normalized_url>
<share_count>6244</share_count>
<like_count>1513</like_count>
<comment_count>1391</comment_count>
<total_count>9148</total_count>
<click_count>4007</click_count>
<comments_fbid>433841427570</comments_fbid>
<commentsbox_count>4</commentsbox_count>
</link_stat>
</links_getStats_response>
Hope this helps.
Also,
If you want that response as a JSON, just append &format=json
to request URL – Dexter

You need to use Facebooks' FQL with table link_stat. Use something similar to this
SELECT
url, normalized_url,
share_count, like_count, comment_count, total_count,
commentsbox_count, comments_fbid, click_count
FROM link_stat
WHERE url="http://www.imdb.com/title/tt0117500/"
This is the result for that query (in XML format, you can of course get it in JSON)
<?xml version="1.0" encoding="UTF-8"?>
<fql_query_response xmlns="http://api.facebook.com/1.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" list="true">
<link_stat>
<url>http://www.imdb.com/title/tt0117500/</url>
<normalized_url>http://www.imdb.com/title/tt0117500/</normalized_url>
<share_count>6233</share_count>
<like_count>9500</like_count>
<comment_count>2179</comment_count>
<total_count>17912</total_count>
<commentsbox_count>6</commentsbox_count>
<comments_fbid>380728101301</comments_fbid>
<click_count>164</click_count>
</link_stat>
</fql_query_response>
The total_count (17912) is the number you are looking for.
