#create_endpoint(endpoint_name: '', account_name: '', version: '') ⇒ Mindee::HTTP::Endpoint

Creates a custom endpoint with the given values. Do not set for standard (off the shelf) endpoints.

Parameters:

  • endpoint_name (String) (defaults to: '') —

    For custom endpoints, the "API name" field in the "Settings" page of the API Builder. Do not set for standard (off the shelf) endpoints.

  • account_name (String) (defaults to: '') —

    For custom endpoints, your account or organization username on the API Builder. This is normally not required unless you have a custom endpoint which has the same name as a standard (off the shelf) endpoint.

#enqueue(input_source, product_class, endpoint: nil, all_words: false, full_text: false, close_file: true, page_options: nil, cropper: false) ⇒ Mindee::Parsing::Common::ApiResponse

Enqueue a document for async parsing

Doesn't need to be set in the case of OTS APIs.

Parameters:

  • product_class (Mindee::Inference) —

    class of the product

  • input_source (Mindee::Input::Source::LocalInputSource, Mindee::Input::Source::UrlInputSource)
  • endpoint (HTTP::Endpoint, nil) (defaults to: nil) —

    Endpoint of the API.

  • all_words (Boolean) (defaults to: false) —

    Whether to extract all the words on each page. This performs a full OCR operation on the server and will increase response time.

  • full_text (Boolean) (defaults to: false) —

    Whether to include the full OCR text response in compatible APIs. This performs a full OCR operation on the server and may increase response time.

  • close_file (Boolean) (defaults to: true) —

    Whether to close() the file after parsing it. Set to false if you need to access the file after this operation.

  • page_options (Hash, nil) (defaults to: nil) —

    Page cutting/merge options:

    • :page_indexes Zero-based list of page indexes.
    • :operation Operation to apply on the document, given the `page_indexes specified:
      • :KEEP_ONLY - keep only the specified pages, and remove all others.
      • :REMOVE - remove the specified pages, and keep all others.
    • :on_min_pages Apply the operation only if document has at least this many pages.
  • cropper (Boolean) (defaults to: false) —

    Whether to include cropper results for each page. This performs a cropping operation on the server and will increase response time.
