The content fetching services

The currently available content fetching services in WidSets:

Type	Fetched	Function
syndication	yes	Delivers syndication (RSS/RDF/ATOM) feed content. Returns predefined fields from the feed. You can use TOKEN authentication with the feeds. (See Token authentication.)
webfeed	yes	Delivers customized syndication feed content. Any fields in the structured source document can be referenced and returned by the service in a controlled fashion. (See Advanced filters.)
image	no	Returns scaled images to the script. The images are normally scaled, converted to 8 bit indexed color and encoded to PNG format. You can get custom size images with a bounding box.
http	no	Executes HTTP fetches. HTTP GET, HTTP POST. Parameters can be input separately so they can be URLEncoded. The content is returned in String or Binary format depending on the source. A filter can be applied to the content that is returned. (See Advanced filters.)

For more detailed descriptions of each service, please check their own articles.
