Part 2. Pros & Cons of Mistral OCR

Mistral OCR looks like an exceptional OCR tool for processing documents and images, but let's evaluate its features ourselves. Check out the below steps to learn how to use Mistral OCR and what to expect:

Step 1. Mistral OCR API Setup

The first thing we have to do is set up the API key. To do so, visit the Mistral API key page and click on "Create new key". You have to give a key a name and an expiry date.

After creating the key, copy it and create a ".env" file located in the same directory where you will add the script.

The format should look like this:

MISTRAL_API_KEY=<your_api_key_here>

Step 2. Python Environment Setup

Next, you have to install the below packages to use Mistral OCR API with Python:

• mistralai: Official client to communicate with Mistral's API.
• python-dotenv: Loads environment variables from the .env file.
• datauri: Helps process image data and convert them into a suitable format.

Use this command to install all required packages:

pip install mistralai python-dotenv datauri

Once your environment is ready and the API key is in place, you're all set to begin using Mistral OCR.

Step 3. Perform OCR by Sending Document URL

Below is the code that performs an OCR on a document extracted from a URL. It first sends the document URL to execute OCR and then prints the structured markdown content.

import os
from mistralai import Mistral

class SimpleOCRAgent:
    def __init__(self, api_key):
        self.client = Mistral(api_key=api_key)
    
    def process_document(self, document_url):
        response = self.client.ocr.process(
            model="mistral-ocr-latest",
            document={
                "type": "document_url",
                "document_url": document_url
            },
            include_image_base64=True
        )
        return response

if __name__ == "__main__":
    api_key = os.environ.get("MISTRAL_API_KEY")
    if not api_key:
        raise ValueError("Please set the MISTRAL_API_KEY environment variable.")
    
    agent = SimpleOCRAgent(api_key=api_key)
    document_url = "https://arxiv.org/pdf/2201.04234"  # Change as needed
    result = agent.process_document(document_url)
    print("OCR Result:")
    print(result)

Code Explanation

• Initialization: The agent starts by loading the API key to authenticate with Mistral OCR services.
• Document Processing: It uses the process_document method to submit a document URL to the OCR engine.
• Result Output: The response includes structured OCR data in markdown format, which combines extracted text and metadata for easy readability.

This way, we can run different code snippets to use Mistral OCR for different scenarios.
