Mindee API Helper Library for Ruby

Quickly and easily connect to Mindee's API services using Ruby.

Requirements

The following Ruby versions are tested and supported: 2.6, 2.7, 3.0, 3.1, 3.2

Quick Start

Here's the TL;DR of getting started.

First, get an API Key

Install by adding this line to your application's Gemfile:

gem 'mindee'

And then execute:

bundle install

Finally, Ruby away!

Environment Variables

This library offers customizable features through environment variables. While there may be instances where you need to
rely on them, it's crucial to exercise caution when modifying them to avoid unintended consequences.

If you're unsure whether you need to adjust these variables, it's advisable to refrain from doing so unless you have a
specific reason. Accidentally overwriting them can lead to unexpected behavior.

Before making any changes, we recommend reviewing the following information to understand the purpose and potential
impact of each environment variable:

MINDEE_API_KEY:
- Description: Your personal Mindee API Key as shown on the platform. Be careful not to show this publicly!
- Default Value: nil
MINDEE_BASE_URL:
- Description: The default base URL of the API endpoint. Use this variable to specify the root URL for API requests. Modify as needed for proxy configurations or changes in API endpoint location.
- Default Value: https://api.mindee.net/v1
MINDEE_REQUEST_TIMEOUT:
- Description: The default timeout for HTTP requests (in seconds).
- Default Value: 120

Loading a File and Parsing It

Global Documents

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')
result = mindee_client.parse(
  input_source,
  Mindee::Product::Invoice::InvoiceV4
)

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

Note: Files can also be loaded from:

A URL (https):

input_source = mindee_client.source_from_url("https://my-url")

A bytes input stream:

input_source = mindee_client.source_from_bytes('/path/to/the/file.ext', "name-of-my-file.ext")

A base64 encoded string:

input_source = mindee_client.source_from_b64string('/path/to/the/file.ext', "name-of-my-file.ext")

A ruby file object:

input_source = mindee_client.source_from_file(input_file, "name-of-my-file.ext")

Region-Specific Documents

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')

result = mindee_client.parse(
  input_source,
  Mindee::Product::EU::LicensePlate::LicensePlateV1
)

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

Custom Document (API Builder)

require 'mindee'

# Init a new client and configure your custom document
mindee_client = Mindee::Client.new(api_key: 'my-api-key')
endpoint = mindee_client.create_endpoint(
  endpoint_name: 'my-endpoint',
  account_name: 'my-account'
)

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

result = mindee_client.parse(
  input_source,
  Mindee::Product::Custom::CustomV1,
  endpoint: endpoint
)

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

# Looping over all prediction values
result.document.inference.prediction.fields.each do |field_name, field_data|
  puts field_name
  puts field_data.values
  puts field_data.to_s
end

CLI Tool

A command-line interface tool is available to quickly test documents:

ruby ./bin/mindee.rb invoice path/to/your/file.ext

Using the ruby bundler:

bundle exec ruby ./bin/mindee.rb invoice path/to/your/file.ext
