What you get

Full-Text RSS 3.2 from FiveFilters.org includes:

• Easy installation (no database setup required)
• Technical support
• Free updates for 1 year (half price after that)
• Custom site pattern for a site of your choice *
• Full source code

* If extraction does not work well on a particular site, contact us with details of what you're trying to extract and we'll send you a custom site config file (for one site only).

After paying you will automatically receive an email with a download link to the zip package. The zip package contains a readme file with instructions for uploading the code to your web host via FTP.

Older versions

Older versions of Full-Text RSS — without site-specific extraction rules — can be downloaded free of charge from our code repository.

Note: we do not offer any support for these and for best extraction results we recommend buying the latest version.

Hosted or self-hosted?

We want our users to be free to examine and run the code behind FiveFilters.org however they like. So rather than simply invite you to sign up for our premium hosted plan, we've gone to great effort to make the software easy to use and install on your own hosting account.

Using our hosted service (Free, Premium) is the easiest option as we manage everything. You do not have to worry about staying up to date because we maintain the code and any changes we make will automatically be made available to you.

If, however, you have your own hosting account or manage your own server, the self-hosted option gives you the freedom to run the code and manage things yourself — including writing custom extraction rules. We also have a help page on hosting options which should help you get started.

Note: We monitor our hosted service to prevent abuse. For developers needing to process very large amounts of data, we highly recommend downloading the self-hosted version.

API

To extract content from a web page or to transform an existing partial feed to full text, pass the URL (encoded) in the querystring to the following URL:

• http://fivefilters.org/content-only/makefulltextfeed.php?url=[url]

If you have premium access, add your API key to the querystring:

• http://fivefilters.org/content-only/makefulltextfeed.php?key=[key]&url=[url]
• http://fivefilters.org/content-only/makefulltextfeed.php?key=[key]&max=[number of feed items]&url=[url]

If you're self-hosting, replace the base URL with the location you installed Full-Text RSS. Our help page has more details on query string parameters you can use.

System requirements

PHP 5.2 or above is required. The code has been tested on local, shared hosting and cloud environments. We recommend you download and run our simple compatibility test before purchasing. It's a single (zipped) PHP file you can upload to your server and access through your browser. It will tell you whether your server is capable of running Full-Text RSS.

On our help site, we have a list of recommended hosts.

Software Components

Full-Text RSS is written in PHP and relies on the following primary components:

• PHP Readability
• SimplePie
• FeedWriter
• Humble HTTP Agent

Depending on your configuration, these secondary components may also be used:

• html5lib
• htmLawed
• Rolling Curl
• Zend Cache
• Text_LanguageDetect (or PHP-CLD if available)

Featured article

The Five Filters project aims to promote independent, non-corporate media. The free service we provide will include a text link to a featured article, video or website, as well as this website, at the bottom of every feed item.

The current featured article is 'You Say What You Like, Because They Like What You Say' by Medialens.
