FeedAgg Blog

We want to make it is as easy as possible for our publishers to get their content on FeedAgg.com to get exposure and audiences.  To help with that we announced the start of a feed posting API almost a year ago. We have since then rewritten it in a more formal restful API interface.  Below you will find the basics for using it. Feed content policies still apply. Please give us any feedback, good or bad, on how it works for you.

Background

Feed addition requests can be posted to http://www.feedagg.com/add_feed_api.php. You will receive the response as xml containing either a success code(200) or error code(400′s and 500′s).  Successful posts will include the FeedAgg.com url for your feed.

* The API is in a very beta stage and error status codes (ie >200) may change. *

Error codes are 400′s and 500′s. Success codes are 200′s.

A minimum of one tag per feed is required, max 100 50.

Feed submissions via API require a username.

URL Encode your feed urls.

Tags are separated by commas when submitting via API.

Rate limiting still applies. Currently set at 60 submissions per minute.

Updated: 2/10/11

Variables

FeedURL (Required, URL Encoded)

Tags (A minimum of one tag per feed is required, max 100 50.)

UserName (Required)

Example Successful Submission XML Response

<?xml version="1.0" encoding="UTF-8"?>
<response>
     <status_code>200</status_code>
     <status_txt>Your feed, FeedAgg Blog, has been saved.</status_txt>
     <data>
          <title>FeedAgg Blog</title>
          <submitted_url>http://www.feedagg.com/blog/feed/</submitted_url>
          <feedagg_url>http://www.feedagg.com/feed/258970/FeedAgg</feedagg_url>
          <feedagg_id>258970</feedagg_id>
     </data>
</response>

Example PHP(v5.0) Code To Submit VIA API

//---------------------------------------------------------------------------------
// The feedagg.com API address
 $url = 'http://www.feedagg.com/add_feed_api.php';
// Set up and execute the curl process
 $curl_handle = curl_init();
 curl_setopt($curl_handle, CURLOPT_URL, "$url");
 curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
 curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($curl_handle, CURLOPT_POST, 1);
 curl_setopt($curl_handle, CURLOPT_POSTFIELDS, "FeedURL=".urlencode('http://www.feedagg.com/blog/feed/')."&Tags=tag1,tag2&UserName=<yourusername>");
 $buffer = curl_exec($curl_handle);
 curl_close($curl_handle);

// check for success or failure
 if (empty($buffer))
 {
      echo 'message' . "<br>";
 }
 else
 {
      echo 'success' . "<br>";
 }

//load to xml obj
 $xml = simplexml_load_string($buffer);

//sample results
 echo "code " . $xml->status_code . "<br>";
 echo "message " . $xml->status_txt . "<br>";
 echo "title " . $xml->data->title . "<br>";
 echo "submitted_url " . $xml->data->submitted_url .  "<br>";
 echo "feedagg_url " . $xml->data->feedagg_url . "<br>";
 echo "feedagg_id " . $xml->data->feedagg_id . "<br>";
