Wolfram can thank Apple for some of his search engine's recent popularity as Siri uses the databases to offer comparisons asked for by iPhone 4S users. Wolfram Alpha differs from other search engines in that its results are based on data curated by Wolfram Alpha, not on algorithms attempting to sort the Web like Google or Bing.ĭespite early criticism of Wolfram Alpha's self-described "computational knowledge engine," including its initial focus on mathematical and scientific data, the once-small company has grown to a team of over 200 and is on the cusp of releasing Wolfram Alpha Pro, which company creator Stephen Wolfram calls "Step 2, the next step of what can be done with this approach." Your AppID is typed correctly and that your appid parameter is using the correct syntax.According to a report by the New York Times, nearly 25 percent of the traffic handled by search engine Wolfram Alpha comes from Siri, Apple's voice-controlled personal assistant software.Īpple announced a partnership with Wolfram Alpha in October when it released the iPhone 4S and introduced Siri. This error is returned when a request does not contain any option for the appid parameter. Your AppID is typed correctly and that your appid parameter is using the correct syntax. This error is returned when a request contains an invalid option for the appid parameter. In most cases, this canīe fixed by checking that you have used the correct syntax for including the i parameter. This status indicates that the API did not find an input parameter while parsing. You may occasionally receive this status when requesting information on topics that are restricted or not covered. This is commonly caused by input that is blank, misspelled, poorly formatted or otherwise unintelligible. This status is returned if a given input value cannot be interpreted by this API. &i=What+airplanes+are+flying+overhead%3F &timeout=5 Errors HTTP Status 501 It is primarily used to optimize response times in applications, although it may also affect the number and type of results returned by the Simple API. This parameter specifies the maximum amount of time (in seconds) allowed to process a query, with a default value of "5".
WOLFRAM ALPHA SERIES
The other option, labelbar, specifies a series of separate content sections with label bar headings: &i=What+airplanes+are+flying+overhead%3F &layout=labelbar Show Output The default setting is divider (shown in previous queries), which specifies a series of pods with horizontal dividers.
WOLFRAM ALPHA FULL
layoutįor API types that return full Wolfram|Alpha output, the layout parameter defines how content is presented. Since its output often includes a mix of text, images and layout elements, the Simple API will accept a number of parameters, listed below. You can add URL-encoded parameters to customize output. When executed with a valid AppID, this URL will return an image with informational elements relating to the input: For instance, here is a queryįor "What airplanes are flying overhead?": &i=What+airplanes+are+flying+overhead%3F Next, use the i parameter to specify the URL-encoded input for your query.
The appid parameter tells your query which AppID to use: ?appid=DEMO The base URL for queries is: Įvery query requires two pieces of information-an AppID and an input value-in order to be processedĬorrectly. Now that you have an AppID, you can make your first query.
