Accessing the Service

You access Document Understanding using the Console, REST API, SDK, or CLI.

Use the following options to access Document Understanding

Pick an option, based on your preference and its suitability, for the task you want to complete:
  • The Oracle Cloud Infrastructure Console is an easy-to-use, browser-based interface. To access the Console, you must use a supported browser.
  • The REST APIs provide the most functionality, but require programming expertise. API reference and endpoints provide endpoint details and links to the available API reference documents including the Artificial Intelligence Services REST API.
  • Oracle Cloud Infrastructure provides SDKs that interact with Language without the need to create a framework.
  • The CLI provides both quick access and full functionality without the need for programming.
Note

Document Understanding isn't supported in the Oracle Always Free Tier.
