Once you have set up your account, take some time to explore the features, models, and extensive documentation that AI21 Studio offers. This foundational knowledge will be invaluable as you move forward.

Obtaining Your API Key

After familiarizing yourself with the platform and its offerings, you will need to obtain your API key. This key is essential for accessing the API in your development projects, ensuring secure and authenticated interactions with the AI21 services.

Exploring the Contextual API

The Contextual Answers API is a notable feature of AI21 Studio that enables precise answer generation based on specific document context. Unlike traditional models, this API ensures that responses are exclusively derived from the provided context, mitigating the risk of factual inaccuracies.

Key Features of the Contextual Answers API

• Context-Based Responses: Guarantees that answers stem directly from user-defined context.
• Task-Specific Optimization: Designed for efficiency with no need for complex prompt engineering.
• User-Friendly: Streamlined integration into existing systems, making it easy for developers.

Required Parameters for API Requests

To utilize the Contextual Answers API successfully, you must provide two parameters:

1. context: A string representing the textual context for the question asked.
2. question: A string that forms the basis of your inquiry related to the context provided.

Understanding the API Response

The API's response includes:

• answer: A string with the answer derived from the context, or null if no answer is found.
• id: A unique identifier for tracking the request, especially useful when handling multiple queries.

Setting Up Your Project

The setup process begins with installing Flask, a lightweight web framework in Python that provides the structure for your application.

pip install Flask

Postman is another critical tool that simplifies API management and testing, allowing you to create and modify requests effortlessly.

Creating Your Flask Application

Start by creating a new Python file named app.py and populate it with essential boilerplate code. Here's a minimal template to get you started:

from flask import Flask, request, jsonify

app = Flask(__name__)

if __name__ == '__main__':
    app.run(debug=True)

Implementing the API Functionality

After establishing the basic structure, you can proceed to integrate the AI21 API. Modify the get_answer() function according to the API guidelines, ensuring you securely handle your API key:

def get_answer():
    # Load API key from environment variable
    # Set up your context and question
    context = request.json['context']
    question = request.json['question']
    url = ""  # Insert API URL here
    payload = {"context": context, "question": question}
    headers = {"Authorization": f"Bearer {API_KEY}"}
    
    response = requests.post(url, json=payload, headers=headers)
    return jsonify(response.json())

Testing Your Application Using Postman

Once your application code is ready, you can test it in Postman. Run your Flask app using:

python app.py

In Postman, create a POST request with your context and question parameters to see the AI21 API's outputs.

Conclusion and Next Steps

This tutorial provided an introductory guide to creating a Flask web API for contextual answers utilizing AI21 Studio's Contextual Answers API. With further enhancements, you could evolve this backend solution into a full-fledged application with a user-friendly frontend.
