Wolfram|Alpha – Wolfram|Alpha API

Wolfram|Alpha API

Bring computational knowledge to your web, mobile, desktop, and enterprise applications

Access the Wolfram|Alpha platform at multiple levels—from individual results to complete Wolfram|Alpha output pages. The API operates as a high-performance REST-style webservice, with convenient bindings for popular languages and platforms.

Free-Form Linguistic Input

A new way to interact with the power of Mathematica: enter plain English; get immediate results and the Mathematica input for further exploration.

Combine Knowledge and Computation

Inject Wolfram|Alpha's vast knowledge directly into the Mathematica workflow, providing curated data for your computations, analysis, and development.

Access the Wolfram|Alpha platform at multiple levels - from individual results to complete Wolfram|Alpha output pages. The API operates as a high-performance REST-style webservice, with convenient bindings for popular languages and platforms.


Two popular integrations are Microsoft BING Search Engine and TouchPress E-Books

API Language Libraries

The Wolfram|Alpha webservice API can be accessed from any language that supports web requests and XML. Use these language bindings to get a quick start in many popular languages. SOAP is not planed so far.

  • .NET Binding
  • Perl Binding
  • Python Binding
  • Ruby Binding
  • PHP Binding
  • Java Binding

API Explorer

The API Explorer shows for a developer what the API is answering, if you call them. The API-response es presented in sourcecode view (Images, Plaintext, HTML, ...).

Wolfram|Alpha Widgets

Widgets are mini-apps built on top of Wolfram|Alpha queries. You can build your own, or find useful widgets in the Widget Gallery. Share them in Facebook, Twitter, email, or anywhere else. Some samples are " Distance to moon", "speedcalculation", "Pythagoras Tree Variations", "Exchange rates", "loan calculator", ...

Wolfram|Alpha Licensing

The free-form input within Mathematica (through the built-in "=") and the use of Wolfram|Alpha queries within Mathematica (through the built-in "==") - both shortly called "Wolfram|Alpha API calls" henceforth - are both limited by the number of calls AND the age of the Mathematica license. For normal, non-commercial or non-automated calls - ADDITIVE thinks - the maximum number of API calls represents no limit. On our web page of Mathematica types the maximum number of Wolfram|Alpha API calls per time unit (day, month) for the current Mathematica version is listed.

Wolfram|Alpha API access is supported for licenses that are within two (2) major upgrades of the current version, or up to one (1) year following purchase, whichever is greater. The allowances apply to the combined number of calls from the license plus any linked home-use licenses obtained through Premier Service or Site Premier Service.

Usage of free-form input, Wolfram|Alpha queries, and the Wolfram|Alpha function are subject to the Mathematica License Agreement & Wolfram|Alpha Terms of Use

Mathematica Home Use: The access is linked to the main Mathematica license.
