) calls a Wolfram API that has apiname with any number of parameters. The HTML alt text for the image is usually the same text returned by using the plaintext format option. WolframAPI (String apiname, Parameter (name1, value1), Parameter (name2, value2). The source link given in the tag is a simplified version of the Wolfram|Alpha web output: Here is the query to retrieve only the image portion of the "solve 3x-7=11" result from the above: &format=image You can opt to return only one of these by specifying either image or plaintext with the format parameter. For example, this query would generate a Result pod with 3 additional steps: ‐by‐step notation makes URLs substantially shorter and easier to parse in multi-step applications.īy default, results returned by the Show Steps API are presented both as a linked image and as a snippet of plain text. In this situation, you can prepend to indicate multiple state changes in one podstate parameter. Note that the new element named "Next step" is identical to the one in the previous step. To access a subsequent state, append an additional instance of the podstate parameter: ‐by‐step &podstate=Next%20step Ĭount the total valence electrons of the hydrogen (n_H,val = 1) and oxygen (n_O,val = 6) atoms: In this case, the API has generated an additional pod state to show further steps in the process. Start by drawing the overall structure of the molecule: Passing this input value into a new query generates a new version of the pod:ĭraw the Lewis structure of water. For instance, the result for the "water molecule" query contains a "Structure diagram" pod with a step-by-step explanation of the chemical structure diagram: In some cases, the API may generate additional pod states to show further steps in a process. The Fast Query Recognizer API returns a raw XML or JSON response telling whether a query would be accepted by the WolframAlpha server, and from what domain the. These APIs are free to use for up to 2,000 calls per month. If no result returns, it will try the Short Answers API automatically. This uses spokenresults method to get a text string from the Spoken Result API. Here is the result from above, but with a "Possible intermediate steps" subpod contained in the Result pod: &podstate=Step-by-step%20solution In test.py, replace the key value with your WolframAlpha API key, then run: python test.py. This converts all eligible result pods to their step-by-step forms. To show the steps for a result, pass the name value from the element-usually "Step-by-step%20solution" or just "Step-by-step"-to the podstate parameter. (For more on pods, see this in-depth explanation.) The next section describes how to use these result elements in conjunction with basic URL parameters to get step-by-step solutions. Any pod containing such an element can be altered to show the steps for computing the answer. For example, here is the URL and full output for the "solve 3x-7=11" query: &input=solve+3x-7%3D11 Įxamining this XML, you can see that the Result pod has a element named "Step-by-step solution". The best way to determine what is needed for a particular query is to first perform a Full Results API query and inspect the XML results for the desired elements. Parameter options for the Show Steps API will vary depending upon the type and subject of the query. The Show Steps API provides programmatic access to these step-by-step solutions using a small subset of parameters available through the Full Results API. Many Wolfram|Alpha web results include a button labeled "Step-by-step solution":Ĭlicking this button brings up an interactive dialog that allows the user to view the computational steps that lead to the displayed result: When executed with a valid AppID, this URL will return an XML result with the full solution: For instance, here is the query to show the steps for "solve 3x-7=11" in a plain text format: &podstate=Result_Step-by-step+solution&format=plaintext XmlHttp.The rest of the URL uses specific parameters to extract the desired step-by-step solution.
