I was looking for a service (with API) where I can ask it a general question (aka, when was Einstein born?) and retrieve an answer from the Web.

Is there any available service to do that? Have tried Watson services but didn't work as expected.


  • OK if it supports only English? What is your budget and volume? – Nicolas Raoul Nov 9 '16 at 11:45
  • Yup it's okay, I need for a small experiment – user3607093 Nov 9 '16 at 16:18
  • Please add this information into your question (edit it), comments get deleted. Thanks! – Nicolas Raoul Nov 10 '16 at 3:24
  • What is didn't work as expected? What output format do you want, JSON? Please edit your question – user416 Nov 11 '16 at 14:32

There is Wolfram Alpha.

This is essentially a search engine with significant internal intelligence.

It has an API and can be embedded in web pages. Its output can be textual or graphical.

Furthermore, there are apps for phones & tablets to interact with the knowledge base.

You have tagged your question . The API is free for "personal and experimental" use, if you wish to make extensive and/or commercial use you will have to pay.
