*In this tutorial, you will learn how to use Q&A API in 5 minutes using Python. Eden AI provides an easy and developer-friendly API that allows you to ask questions based on texts.*

## **What is [Question Answering API](http://www.edenai.co/feature/question-answering?referral=how-to-QA-python)?**

Question Answering API allows users to input a natural language question and receive an answer based on the information present in a specific set of documents or a knowledge base. This technology uses natural language processing (NLP) and machine learning (ML) to understand the user's question and find the most relevant answer:

## **How to use Q&A API with Python**

You are now ready to process text into Eden AI Q&A API. You can process Q&A in many languages. You can access the list of languages supported in our documentation [here](https://docs.edenai.co/reference/text_question_answer_create?referral=how-to-QA-python).


### **1. Get a Q&A API Key on Eden AI**

To perform Q&A, you'll need to create an account on [Eden AI](https://app.edenai.run/user/register?referral=how-to-QA-python) for free. Then, you will be able to get your **API key** direclty from the homepage with free credits offered by Eden AI.

### **2. Let’s use Question Answering API**

Now that you have imported packages on Python and got your API key, you will be able to search infos into your text. With Eden AI, you can choose from a wide range of engine you want for Q&A. You can access all the Q&A providers available on Eden AI [here](https://docs.edenai.co/reference/text_question_answer_create?referral=how-to-QA-python).


Here is the Python script you'll need to write on your notebook:

For example, we called two different Q&A engines. Eden AI API will then return in its JSON response results of those providers.

Once the request is done, you will be able to get the result with this print:
