Quick-Start

Using the sample below, we are going to illustrate how to extract the data that we want using the SDK.

Sample Code

using Mindee;
using Mindee.Input;
using Mindee.Product.Invoice;

string apiKey = "my-api-key";
string filePath = "/path/to/the/file.ext";

// Construct a new client
MindeeClient mindeeClient = new MindeeClient(apiKey);

// Load an input source as a path string
// Other input types can be used, as mentioned in the docs
var inputSource = new LocalInputSource(filePath);

// Call the API and parse the input
var response = await mindeeClient
    .ParseAsync<InvoiceV4>(inputSource);

// Print a summary of all the predictions
System.Console.WriteLine(response.Document.ToString());

// Print only the document-level predictions
// System.Console.WriteLine(response.Document.Inference.Prediction.ToString());

You can also call this product asynchronously:

using Mindee;
using Mindee.Input;
using Mindee.Product.Invoice;

string apiKey = "my-api-key";
string filePath = "/path/to/the/file.ext";

// Construct a new client
MindeeClient mindeeClient = new MindeeClient(apiKey);

// Load an input source as a path string
// Other input types can be used, as mentioned in the docs
var inputSource = new LocalInputSource(filePath);

// Call the product asynchronously with auto-polling
var response = await mindeeClient
    .EnqueueAndParseAsync<InvoiceV4>(inputSource);

// Print a summary of all the predictions
System.Console.WriteLine(response.Document.ToString());

// Print only the document-level predictions
// System.Console.WriteLine(response.Document.Inference.Prediction.ToString());

Sample Output (rST)

Standard Fields

These fields are generic and used in several products.

BaseField

Each prediction object contains a set of fields that inherit from the generic BaseField class. A typical BaseField object will have the following attributes:

• Confidence (double?): the confidence score of the field prediction.

• BoundingBox (BoundingBox): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.

• Polygon (Polygon): contains the relative vertices coordinates (Polygon extends List<Point>) of a polygon containing the field in the image.

• PageId (int?): the ID of the page, always null when at document-level.

A Point simply refers to a List of double.

Aside from the previous attributes, all basic fields have access to a custom ToString method that can be used to print their value as a string.

AddressField

Aside from the basic BaseField attributes, the address field AddressField also implements the following:

• StreetNumber (string): String representation of the street number. Can be null.

• StreetName (string): Name of the street. Can be null.

• PoBox (string): String representation of the PO Box number. Can be null.

• AddressComplement (string): Address complement. Can be null.

• City (string): City name. Can be null.

• Postalcode (string): String representation of the postal code. Can be null.

• State (string): State name. Can be null.

• Country (string): Country name. Can be null.

The Value field of an AddressField should be a concatenation of the rest of the values.

AmountField

An amount field AmountField extends BaseField, but also implements:

• Value (double?): corresponds to the field value. Can be null if no value was extracted.

ClassificationField

The classification field ClassificationField extends BaseField, but also implements:

• Value (strong): corresponds to the field value.

A classification field's value is always a string.

CompanyRegistration

Aside from the basic BaseField attributes, the company registration field CompanyRegistration also implements the following:

• Type (string): the type of company.

• Value (string): corresponds to the field value.

• ToTableLine(): a method that formats the data to fit in a .rst display.

StringField

The text field StringField extends BaseField, but also implements:

• Value (string): corresponds to the field value.

• RawValue (string): corresponds to the raw value as it appears on the document.

DateField

The date field DateField extends StringField, but also implements:

• DateObject (DateTime?): an accessible representation of the value as a C# object. Can be null.

Locale

The locale field Locale extends BaseField, but also implements:

• Language (string): ISO 639-1 language code (e.g.: en for English). Can be null.

• Country (string): ISO 3166-1 alpha-2 or ISO 3166-1 alpha-3 code for countries (e.g.: GRB or GB for "Great Britain"). Can be null.

• Currency (string): ISO 4217 code for currencies (e.g.: USD for "US Dollars"). Can be null.

PaymentDetail

The payment details field PaymentDetail extends BaseField, but it also implements:

• AccountNumber (string): number of an account, expressed as a string. Can be null.

• Iban (string): International Bank Account Number. Can be null.

• RoutingNumber (string): routing number of an account. Can be null.

• Swift (string): the account holder's bank's SWIFT Business Identifier Code (BIC). Can be null.

Taxes

Tax

Aside from the basic BaseField attributes, the tax field Tax also implements the following:

• Rate (double?): the tax rate applied to an item expressed as a percentage. Can be null.

• Code (string): tax code (or equivalent, depending on the origin of the document).

• Base (double): base amount used for the tax. Can be null.

• Value (double): the value of the tax. Can be null.

Currently TaxField is not used on its own, and is accessed through a parent Taxes object, an array-like structure.

Taxes (List)

The Taxes field represents a List of Tax objects. As it is the representation of several objects, it has access to a custom ToString method that can render a Tax object as a table line.

Specific Fields

Fields which are specific to this product; they are not used in any other product.

Line Items Field

List of all the line items present on the invoice.

A InvoiceV4LineItem implements the following attributes:

• Description (string): The item description.

• TaxRate (double): The item tax rate in percentage.
