How to Set Up Mistral OCR API in Your Workflow for Document Understanding

Learn how to integrate Mistral OCR API into your workflow for accurate document understanding, including tables, figures, and multilingual text extraction.

What is Mistral OCR?

Mistral OCR is the world’s best document understanding API, capable of extracting text from tables, figures, equations, and even scanned documents. Whether it’s invoices, textbooks, or multilingual content like Hindi, Mistral OCR delivers precise results. In this guide, we’ll walk you through setting up Mistral OCR API in your workflow step by step.

Why Do We Need OCR?

Optical Character Recognition (OCR) is essential when dealing with PDFs, invoices, or scanned documents. Traditional methods of extracting text from PDFs often fail to capture the actual data, returning only field names or headers. Mistral OCR solves this by accurately extracting and translating the content, making it a powerful tool for businesses and developers.

Quick Demo: How Mistral OCR Works

Here’s a quick overview of how Mistral OCR operates in a workflow:

1. Form Submission: Users upload a document (e.g., an invoice) via a form.

2. Upload to Mistral: The document is uploaded to Mistral, and a URL is generated.

3. OCR Results: Mistral processes the document and returns the extracted text in markdown format, including all relevant data.

Step-by-Step Guide to Setting Up Mistral OCR API

Step 1: Get Your Mistral API Key

To get started, visit the Mistral website and click “Try the API.” Create an account, verify your phone number, and select the free experimental plan. Then, generate an API key and store it securely.

Step 2: Set Up a Form Trigger

In your workflow, create a form trigger to allow users to upload documents. For example, set up a form with a single file upload field titled “Invoice.” This form will capture the binary data of the uploaded document.

Step 3: Upload the File to Mistral

Using an HTTP request, upload the binary file to Mistral. Copy the curl command from the Mistral documentation, import it into your workflow, and configure the request with your API key and binary file data.

Step 4: Get the Signed URL

Once the file is uploaded, Mistral returns a unique ID. Use another HTTP request to fetch the signed URL for the document. This URL will be used to perform OCR in the next step.

Step 5: Extract Text with OCR

Finally, send the signed URL to Mistral’s OCR endpoint to extract the text. Configure the HTTP request with the model (Mistral OCR Latest) and the document URL. Mistral will return the OCR results in a structured format.

Extracting Specific Information

After obtaining the OCR results, you can use an AI extractor node to pull specific information, such as invoice numbers or dates. Simply define the attributes you need, and the AI will parse the text accordingly. This data can then be pushed into Google Sheets, sent via email, or integrated into other workflows.

Conclusion

Mistral OCR API is a game-changer for document understanding, offering unmatched accuracy and flexibility.
