Cohere Tutorial: Retrieving Data from Tables with FastAPI

Mastering Cohere and FastAPI: A Comprehensive Tutorial for AI Enthusiasts

In the rapidly evolving world of Artificial Intelligence, understanding how to implement technologies like Cohere and FastAPI can significantly enhance your data management capabilities. This tutorial will provide you with the insights needed to create a FastAPI application that efficiently extracts and processes data from tabular formats using Cohere, a powerful language model API.

Why Use FastAPI and Cohere?

FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.6+ based on standard Python type hints, making it easy to create interactive applications. On the other hand, Cohere provides advanced natural language processing functionalities, which can enhance the intelligence of your applications. Together, they form an exceptional toolset for developers in the AI space.

Getting Started

Let's kick things off by creating a new project. Open your terminal and follow these steps:

1. Create a new directory for your project.
2. Navigate into the directory.
3. Create a .env file to store your Cohere API key.

Next, you'll need to install the necessary libraries. Run the following commands:

pip install fastapi uvicorn cohere dotenv

Setting Up Your FastAPI Application

Once your environment is ready, it’s time to create an app.py file, where you will write the code.

Importing Libraries

from fastapi import FastAPI
import cohere
import os
from dotenv import load_dotenv

Creating the FastAPI Application and Cohere Client

load_dotenv()
app = FastAPI()
cohere_api_key = os.getenv('COHERE_API_KEY')
co = cohere.Client(cohere_api_key)

Defining Sample Data

example_data = [
    {"id": 1, "name": "Alice", "age": 30},
    {"id": 2, "name": "Bob", "age": 25}
]

Creating a Request Handler

Now, you can create an endpoint for your FastAPI application that responds with the sample data:

@app.get("/data")
def get_data():
    return example_data

Running Your Application

To run your application, execute the following in your terminal:

uvicorn app:app --reload

Testing the Application

With your application running, you can navigate to http://127.0.0.1:8000/data in your web browser to test the endpoint. You should see the sample data displayed as JSON. You can also interact with your API by asking questions or making requests to other endpoints.

Conclusion

FastAPI and Cohere combine to create a powerful suite for developing AI applications. With this tutorial, you have learned to set up a basic FastAPI application integrated with Cohere, enabling you to extract and manipulate data seamlessly.
