• assumption - Applies an assumption to the query.
• translation - Used to set the automatic translation to English. Defaults to false
• reinterpret - Used to reinterpret the query if Wolfram | Alpha does not understand. Defaults to false
• primary - Used to display the closest thing to a simple "answer" that Wolfram|Alpha can provide. Defaults to true

getResults(callback)

getQuery(callback)

getPod(callback)

Used to return the Pod from the Query Results

Example Usage

You will need an application ID to access the Wolfram | Alpha API. You can get it by signing up on Wolfram | Alpha Developer

var wolfram = require('./').init('APPLICATION_ID');

var data = {
	
	query : 'pi',
	assumption: '*C.pi-_*Movie-'

};

wolfram.ask(data, function(err, results) {
	if(err)
		throw err;

	//Do something interesting with your data
	//or simply display it
	console.log(util.inspect(results, false, null));
});

wolfram.getPod(function(err, results) {
	if(err)
		throw err;

	//Access the Pods here
	console.log(util.inspect(results, false, null));
});

wolfram.getQuery(function(err, query) { 
	if(err)
		throw err;

	//Returns the Query currently being set
	//	{
	//		input: 'pi',
	// 		assumption: '*C.pi-_*Movie-',
	// 		translation: false,
	// 		reinterpret: false,
	// 		primary: true,
