• An Azure AI services or Document Intelligence resource. Once you have your Azure subscription, create a single-service or Azure AI multi-service resource, in the Azure portal, to get your key and endpoint.

• You can use the free pricing tier (F0) to try the service, and upgrade later to a paid tier for production.

• After your resource deploys, select Go to resource. You need the key and endpoint from the resource you create to connect your application to the Document Intelligence API. You paste your key and endpoint into the code later in the quickstart:

To interact with the Document Intelligence service, you need to create an instance of the DocumentIntelligenceClient class. To do so, you create an AzureKeyCredential with your key from the Azure portal and a DocumentIntelligenceClient instance with the AzureKeyCredential and your Document Intelligence endpoint.

To interact with the Form Recognizer service, you need to create an instance of the DocumentAnalysisClient class. To do so, you create an AzureKeyCredential with your key from the Azure portal and a DocumentAnalysisClient instance with the AzureKeyCredential and your Form Recognizer endpoint.

Add the following code sample to the Program.cs file. Make sure you update the key and endpoint variables with values from your Azure portal Document Intelligence instance:

using Azure;
using Azure.AI.DocumentIntelligence;

//set `<your-endpoint>` and `<your-key>` variables with the values from the Azure portal to create your `AzureKeyCredential` and `DocumentIntelligenceClient` instance

Layout model output

Here's a snippet of the expected output:

  Document Page 1 has 69 line(s), 425 word(s), and 15 selection mark(s).
  Line 0 has content: 'UNITED STATES'.
    Its bounding box is:
      Upper left => X: 3.4915, Y= 0.6828
      Upper right => X: 5.0116, Y= 0.6828
      Lower right => X: 5.0116, Y= 0.8265
      Lower left => X: 3.4915, Y= 0.8265
  Line 1 has content: 'SECURITIES AND EXCHANGE COMMISSION'.
    Its bounding box is:
      Upper left => X: 2.1937, Y= 0.9061
      Upper right => X: 6.297, Y= 0.9061

Here's a snippet of the expected output:

To interact with the Document Intelligence service, you need to create an instance of the DocumentIntelligenceClient class. To do so, you create an AzureKeyCredential with your key from the Azure portal and a DocumentIntelligenceClient instance with the AzureKeyCredential and your Document Intelligence endpoint.

Run the application

After you add a code sample to your application, build and run your program:

1. Navigate to the folder where you have your doc_intel_quickstart.py file.

2. Type the following command in your terminal:

   python doc_intel_quickstart.py
   

To analyze a given file at a URL, you'll use the begin_analyze_document_from_url method and pass in prebuilt-layout as the model Id. The returned value is a result object containing data about the submitted document.

Add the following code sample to your form_recognizer_quickstart.py application. Make sure you update the key and endpoint variables with values from your Azure portal Form Recognizer instance:

Run the application

After you add a code sample to your application, build and run your program:

1. Navigate to the folder where you have your doc_intel_quickstart.py file.

2. Type the following command in your terminal:

   python doc_intel_quickstart.py
   

To analyze a given file at a URI, you'll use the begin_analyze_document_from_url method and pass prebuilt-invoice as the model Id. The returned value is a result object containing data about the submitted document.

Add the following code sample to your form_recognizer_quickstart.py application. Make sure you update the key and endpoint variables with values from your Azure portal Form Recognizer instance:

# import libraries
