| 7 | +The Python OCR SDK supports the [Proof of Address API](https://platform.mindee.com/mindee/proof_of_address). |
| 8 | + |
| 9 | +Using the [sample below](https://github.com/mindee/client-lib-test-data/blob/main/products/proof_of_address/default_sample.jpg), we are going to illustrate how to extract the data that we want using the OCR SDK. |
| 10 | + |
| 11 | + |
| 12 | +# Quick-Start |
| 13 | +```py |
| 14 | +from mindee import Client, PredictResponse, product |
| 15 | + |
| 16 | +# Init a new client |
| 17 | +mindee_client = Client(api_key="my-api-key") |
| 18 | + |
| 19 | +# Load a file from disk |
| 20 | +input_doc = mindee_client.source_from_path("/path/to/the/file.ext") |
| 21 | + |
| 22 | +# Load a file from disk and parse it. |
| 23 | +# The endpoint name must be specified since it cannot be determined from the class. |
| 24 | +result: PredictResponse = mindee_client.parse(product.ProofOfAddressV1, input_doc) |
| 25 | + |
| 26 | +# Print a summary of the API result |
| 27 | +print(result.document) |
| 28 | + |
| 29 | +# Print the document-level summary |
| 30 | +# print(result.document.inference.prediction) |
| 31 | + |

| 97 | +# Field Types |
| 98 | +## Standard Fields |
| 99 | +These fields are generic and used in several products. |
| 100 | + |
| 101 | +### BaseField |
| 102 | +Each prediction object contains a set of fields that inherit from the generic `BaseField` class. |
| 103 | +A typical `BaseField` object will have the following attributes: |
| 104 | + |
| 105 | +* **value** (`Union[float, str]`): corresponds to the field value. Can be `None` if no value was extracted. |
| 106 | +* **confidence** (`float`): the confidence score of the field prediction. |
| 107 | +* **bounding_box** (`[Point, Point, Point, Point]`): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document. |
| 108 | +* **polygon** (`List[Point]`): contains the relative vertices coordinates (`Point`) of a polygon containing the field in the image. |
| 109 | +* **page_id** (`int`): the ID of the page, always `None` when at document-level. |
| 110 | +* **reconstructed** (`bool`): indicates whether an object was reconstructed (not extracted as the API gave it). |
| 111 | + |
| 112 | +> **Note:** A `Point` simply refers to a List of two numbers (`[float, float]`). |
| 113 | +
|
| 114 | + |
| 115 | +Aside from the previous attributes, all basic fields have access to a custom `__str__` method that can be used to print their value as a string. |
| 116 | + |
| 117 | + |
| 118 | +### CompanyRegistrationField |
| 119 | +Aside from the basic `BaseField` attributes, the company registration field `CompanyRegistrationField` also implements the following: |
| 120 | + |
| 121 | +* **type** (`str`): the type of company. |
| 122 | + |
| 123 | +### DateField |
| 124 | +Aside from the basic `BaseField` attributes, the date field `DateField` also implements the following: |
| 125 | + |
| 126 | +* **date_object** (`Date`): an accessible representation of the value as a python object. Can be `None`. |
| 127 | + |
| 128 | +### LocaleField |
| 129 | +The locale field `LocaleField` only implements the **value**, **confidence** and **page_id** base `BaseField` attributes, but it comes with its own: |
| 130 | + |
| 131 | +* **language** (`str`): ISO 639-1 language code (e.g.: `en` for English). Can be `None`. |
| 132 | +* **country** (`str`): ISO 3166-1 alpha-2 or ISO 3166-1 alpha-3 code for countries (e.g.: `GRB` or `GB` for "Great Britain"). Can be `None`. |
| 133 | +* **currency** (`str`): ISO 4217 code for currencies (e.g.: `USD` for "US Dollars"). Can be `None`. |
| 134 | + |
| 135 | +### StringField |
| 136 | +The text field `StringField` only has one constraint: its **value** is an `Optional[str]`. |
| 137 | + |
