The Universal product supports all products in a catch-all generic format, and can be used in the following manner:

Quick-Start

require 'mindee'

# Init a new client
mindee_client = Mindee::Client.new(api_key: 'my-api-key')

# Load a file from disk
input_source = mindee_client.source_from_path('/path/to/the/file.ext')

# Initialize a custom endpoint for this product
custom_endpoint = mindee_client.create_endpoint(
  account_name: 'my-account',
  endpoint_name: 'my-endpoint',
  version: 'my-version'
)

# Parse the file
result = mindee_client.parse(
  input_source,
  Mindee::Product::Universal::Universal,
  endpoint: custom_endpoint
  # Note: On compatible APIs, you can run this HTTP call synchronously by setting `enqueue: false`
)

# Print a full summary of the parsed data in RST format
puts result.document

Universal Endpoints

You may have noticed in the previous step that in order to access a universal build, you will need to provide an account and an endpoint name at the very least.

Although it is optional, the version number should match the latest version of your build in most use-cases.
If it is not set, it will default to "1".

Field Types

Universal Fields

Universal List Field

A UniversalListField is a special type of custom list that implements the following:

• values (Array<StringFieldUniversalObjectField>): the confidence score of the field prediction.
• page_id (Integer): only available for some documents ATM.

Since the inner contents can vary, the value isn't accessed through a property, but rather through the following functions:

• contents_list() (-> Array<String, Float>>): returns a list of values for each element.
• contents_string(separator=" ") (-> String): returns a list of concatenated values, with an optional separator String between them.

  Note: the to_s method returns a string representation of all values of this object, with an empty space between each of them.

Universal Object Field

Unrecognized structures and sometimes values of ListFields are stored in a UniversalObjectField structure, which is implemented dynamically depending on the object's structure.

• page_id ([Integer, nil]): the ID of the page, is nil when at document-level.
• raw_value ([String, nil]): an optional field for when some post-processing has been done on fields (e.g. amounts). nil in most instances.
• confidence ([Float, nil]): the confidence score of the field prediction. Warning: support isn't guaranteed on all APIs.

Other fields:No matter what, other fields will be stored in a dictionary-like structure with a key: value pair where key is a string and value is a nullable string. They can be accessed like any other regular value, but won't be suggested by your IDE.

StringField

The text field StringField only has one constraint: its value is an Optional[str].

Attributes

Universal builds always have access to at least two attributes:

Fields

fields (Hash<String, Array<UniversalListField,UniversalObjectField, (#stringfield)[StringField]>>):
