They also provide information about the basic assumptions and attributes of the response. The results can be sent back asynchronously (additional URLs are provided for pods that haven't been completed yet), and include image data and formatted HTML.Īdditional fields contain things like alternate states of information, such as different precisions of the value of Pi, and can contain links to external information, like satellite images of a geographic area relevant to the query. The XML contains individual "pods" that correspond to the different clusters of information that appear on the results pages that Alpha generates. Formatting a URL to perform a query is very straightforward, and the service returns the results as XML. The API itself is documented in a 34-page PDF. The company has provided a public API for using its service, but users will have to pay fees that add up to a minimum of over two cents a search. The folks behind Wolfram Alpha, a search and computation service, have apparently decided advertising isn't enough. Many of these, however, come with certain display requirements, which allow the service provider to get a bit of free advertising out of the data that's shared. Lots of Web services provide a formal API that allows structured data to be obtained for display on a separate website or via a desktop app. ![]()
